WAIT! If you’re a subscriber reading this in email format, before reading any further, please click on the title of the post right above in order to view the blog in the glory it was meant to have on the actual blog website.

Sometimes you will never know the value of a moment

until it becomes a memory.  ~Dr. Seuss

The weary winter sun is slowly setting behind the frozen horizon, casting a serene purple glow of promise in the golden streaked sky and turning the stark white blanket of snow a rose-colored hue.  The birds have already retired to their secret roosting retreats, but a wise, plump squirrel dines in pensive solitude beneath the icy bird feeder that hangs from the solemn sugar maple.
As each new year begins, I imagine it like a roller coaster slowly and almost peacefully creeping up the hill—then methodically pausing at the very top before careening downward at thrilling speeds to destinations unknown.  It is in that slow deliberate climb and the renewing pause at the top — somewhere within those few quiet moments after the birds have gone to roost and before the sun ducks below the horizon —that I find it gratifying and essential to reflect on the year past.

Sometimes we just need to slow down and take some time to direct our thoughts inward, to dreams and rumination. Out of quiet reflection comes clarity,  boldness for the future and preparedness for the ups and downs of the roller coaster ahead.  And so as 2/14— the day of love—approaches, let’s pause beneath the maple tree to recall and stock up on some of the most beloved memories of 2014 for the Trust’s bird conservation efforts.

Rushton Farm Emerges on the Cutting Edge of Groundbreaking Agroecology Research

In December, an exciting new finding emerged from a team of University of CA, Berkeley researchers showing that organic farming yields are much closer to industrial yields than previously touted.   This new research eliminates the industrial farm bias with an impressive data-set three times larger than previously used.  It basically shows that organic farming yield is only 19 percent less  than conventional (or industrial) farming yields.  This means it is indeed possible to grow food productively while taking care of the land and leaving room for feathered creatures as well!

Furthermore, findings show that the yield gap is greatly reduced or even eliminated when agroecological practices are used.  These practices are all very familiar to our very own Rushton Farm, which is now becoming a model for feeding the world while keeping bird populations healthy!  Such practices harness ecological interactions and include multi-cropping (growing a variety of crops), crop rotation for soil health and promoting native beneficial insects with native wildflower habitat.

Rushton Farm uses many techniques that eliminate the need for chemicals like pesticides by protecting young crops with row cover while they are particularly vulnerable.

This is the kind of farming that provides resiliency to soils, the environment, our health and biodiversity.  It is farming for the future rather than using synthetic chemicals and biologically harmful practices for immediate short-sighted profits.  It is the only kind of farming that can hope to reverse the profoundly   unsustainable impact we are having on this planet, which has lost half of its wildlife populations in 40 years— a result of habitat loss and degradation coupled with unsustainable human consumption (according to WWF’s Living Planet Report 2014).
Although the birds have spoken and we have lots of anecdotal evidence of our own, it’s exciting to have this published confirmation that we’re doing it right and setting a great example at Rushton Farm! Read more about the disappearing yield gap in the following enlightening articles.

Declining Chimney Swifts Successfully Fledge from Rushton’s Brand New Chimney Swift Tower!

One of the many projects that our Bird Conservation Team has developed is the Homeowner Bird Box Program.  Through this wildly popular program, the Trust provides and installs a variety of bird boxes for homeowners, including bluebird, wren, wood duck, kestrel and screech owl boxes.  Bird box experts from the Bird Conservation Team work with the homeowners to devise a plan for the best location of the bird boxes on each property.  Last year, 60 bluebird boxes were installed in Willistown and beyond, successfully pumping out broods of Eastern Bluebirds, Tree Swallows, House Wrens and even some chickadees all summer long, thanks to strategic placement and homeowner cooperation in monitoring their boxes.

However, it was the charming Chimney Swift chicks that stole the show last breeding season.  In response to growing research indicating that swift populations have been suffering a steep decline of 65% since the 1960s due to habitat loss, our Bird Conservation Team decided to include them in our Bird Box Program. This tiny little aerial sprite is often called a “flying cigar”  because of its stubby proportions and smudge-gray color; its feet are so reduced and claws so long that instead of perching it can only cling to vertical walls of chimneys, hollow trees or caves.
After European settlement, the birds became quite adjusted to nesting in chimneys and their population increased accordingly.  Unfortunately, more people cap their chimneys now and other ‘too narrow’ or ‘too slick’ modern chimneys just aren’t as good as the old brick ones for Chimney Swift nesting.  Logging of old growth forests has also contributed to the decline. To help prevent Chimney Swift decline, you can either preserve your chimney or offer the birds a giant fake chimney structure, which is exactly what we did at Rushton last June.
The magnificent wooden tower, meticulously built by a dear neighbor, glowed every summer morning like a golden shrine in the verdant fields of Rushton until one day in July it became the bustling epicenter of a new family of swifts!  You’d think that large structure would be occupied by a colony of swift nests, but unfortunately it’s just one breeding pair per tower.  Nevertheless, the tower’s swift success is more proof that ‘if you build it, they will come,’ and humans can have a positive impact on bird conservation right in their own backyards if they wish.
Check out chimneyswift.org if you’re interested in having your own swift success story.  (I apologize in advance, but all this swift success talk makes me unable to resist: ‘Cause the chimney cappers gonna cap, cap, cap, cap, cap and the loggers gonna log, log, log, log, log… but I’m just gonna build, build, build, build, build… I build a tower, I build a tower.’)

500 School Children Got Feather Prints Left on Their Hearts at the Banding Station

The main purpose of the Rushton banding station is to capture annual data on what bird species are using the preserve during migration and breeding and what effect the sustainable farm and other land management practices have on the bird populations.  Our data is shared with the national bird banding database to contribute to conservation, and —perhaps just as importantly— our “field office” is shared with the public to promote local awareness and enthusiasm for the birds that travel through and dwell in our backyards.

Last year, hundreds of children visited Rushton Farm and the banding station from a variety of public and private schools including some spirited urban groups like the Melton Center’s afterschool New Directions program from West Chester and the Mighty Writers from Philadelphia.  All of the groups gain an understanding of agroecology and farming with a conscience, enjoy an enlightening walk through the cool woodlands, discover the beauty and fragility of the birds up-close at the banding station and then reflect on the harmony of it all in the herb garden.  The emotional impact the trip has on these children can be seen in the photos below.  Some even say that the Rushton field trip is their favorite day of the school year.
The urban students to which nature is a little more unfamiliar were extra fascinated by it all and enjoyed the little wonders they discovered, even if they did endearingly experience them first from behind their cell (read:comfort) phones.

Service Students Went Wild while Helping to Create Winter Bird Habitat

Our service students are of great value to the Willistown Conservation Trust because every year they help our small staff accomplish more than it otherwise could:  repairing tree cages at our preserves, weeding around the office and even planting native wildflowers.  Not only do they get the job done, but they do it with a one-of-a-kind flair that makes it fun and memorable.
Last December, the Shipley students got really creative and built an original bird shelter from large branches and sticks they found around the office.  The shelter is holding up well, strategically propped up against the maple tree from which the feeder hangs.  The birds took to it immediately, and it has been a joy to watch them using it as a perch while they wait in line for the feeder, a shelter from the cold wind and a sanctuary from hawks that patrol the open fields.  Consider building one of your own for your birds this winter!

After that hard work, the students ran wild, exploring in the native wildflower meadow.  They took particular delight and fascination in the old milkweed seed pods.  They opened them up and happily sprinkled them around the meadow so that it looked like it was snowing milkweed seeds!  These are the  moments of magic that a little free time in nature elicits for children, even in a dormant, winter landscape.

Junior Birders Connected to Nature on All New Levels

Our Jr. Birding Club meets monthly to go birding and learn about many other amazing aspects of nature including butterflies and moths, tracks and scat, native plants, bird migration, woodland ecology, farm ecology, stream health, and even bats.   Through a productive combination of structured lessons , free exploration and creative expression—with birds as the backbone— our  Jr. Birders gain a deep appreciation for the natural world and an understanding of the importance of conservation.

Rushton Banding Crew Tirelessly Tagged Nearly 2,000 Birds  during 105 banding days

It was a great year for the banding team; the numbers of birds were up and so were the number of species!  Check out the previous blog post, titled The Spirit of Autumn, to see lots more photos of our beautiful birds.  Below are some photos of the highlights and favorites plus brand new species never before caught at Rushton.

Rushton’s Saw-whet Owl Banding Station had Second-Best Year Yet

Last Fall marked Rushton’s 5th anniversary of monitoring Pennsylvania’s tiniest owls as they disperse south from their coniferous haunts as far north as Canada.  In 34 nights, we captured and banded 96 new Northern Saw-whet Owls, plus caught 3 “foreign recoveries”—owls with bands given to them by other banders before they came to us.  We got all of our foreign birds in November; they included two young females banded earlier that October in New York state 300-some miles away and an older (after second year) female originally banded in Wellington, Canada in 2013!  We also had some exciting reports of owls we banded in years past trying out the nets at other banding stations:  Valhalla, NY had one of our owls— originally banded here in October 2012— last November.

It was an unusual banding season in that the cold weather took its sweet time arriving, and the katydids were still casually singing in mid-November!  Consequently, the owls were fashionably late to their own party.  And then perhaps because the party got started so late, many of the owls did not travel as far south as in previous years.  Most banding stations, especially those south of us—like Virginia, Maryland and Georgia— had below average years.
Not us!  We had our second-best year yet!  Our best was 2012 when we banded a whopping 268 saw-whets after a high-success breeding summer.  In our opening year of 2010 we caught 90 birds, and 2011 and 2013 were the abysmal years of just 33 and 30 birds, respectively.  We and the 130 other banding stations participating in Project Owlnet (which just turned 20) are still trying to learn more about the cyclical nature of this species, how the population is doing and what factors play a role in their winter dispersal movements.

One thing we know is that these little owls are closely dependent, as all birds are, on the reliability of their food sources.  They are rapacious hunters of small rodents, especially mice. Each Saw-whet owl hunts two personal mice per night, saving half of the last one they catch —usually just before dawn— to take with them to their daytime roost site as a “bagged lunch”!  If they can’t get their two mice per night quota… they simply move on to a place with better eats.
Interestingly, an exceptional 23 of our 96 owls caught last fall were caught on multiple nights. This indicates that the eating was good at Rushton, so the owls were able to stick around for awhile.  Our banding records show that 8 of the 23 stayed more than 10 days!  This is as good as getting a 5-star rating on OpenTable, folks!  In addition, a mammal survey carried out by a UPenn graduate student also proved that the Rushton rodents were abundant.
As always, the human density was high during Fall nights at Rushton as well!  Sixteen loyal volunteers and over 700 visitors of all ages were enchanted by our adorable—sometimes demonic as banders will tell you—Saw-whet Owls and learned about the science we and others are doing to fuel the future conservation of these spunky woodland elves.

According to Audubon’s climate model, this owl may be largely absent from the lower 48 during winter by the end of the century, as a result of its winter range steadily marching northward with climate change.  For now though, we can be pretty certain we’ll see these owls again next fall—perhaps in a very big way according to the pattern.  Whoooo knows?  Maybe one is overwintering in a forgotten tangle of honeysuckle in your backyard.

Even on a cold winter’s night as the wild wind howls with disquietude, perusing these photos of warm memories makes me feel as satiated as the plump squirrel beneath the maple tree (you know, the one I mentioned way back at the beginning of this post), stuffing his cheeks full of nourishment in the rose-colored snow beneath the purple sky of promise.
Ignore that groundhog and hold onto your feathers! According to the birds, Spring is just around the corner.

The enchanting little fuzzy phantoms that are now visiting Rushton Woods in thrilling numbers wish you a very Happy Owl-o-Ween!
They also told me to tell you that your young chicks are invited to stop over at Rushton Farm on the night of November 15th from 7-9pm to check out this thing called owl banding during which the humans give each owl a magical silver anklet with numbers on it. The owls say they don’t really care for that part of the night but they’re looking forward to a beautiful performance by one owl in particular, named Ipod, who rumors say can sing all night long at the top of his lungs without getting tired!

Sandy set us back drastically last week with net lanes filled with water and debris, but public songbird migration banding will resume tomorrow, Tuesday (11/6), the last day for the 2012 songbird banding season.  We will open at 5:45am.

The remainder of the fall catch was great with a couple of 80-bird days!  White-throated Sparrows began dominating the bounty in late October along with thrushes including Hermit, Swainson’s and Gray-cheeked.  Dark-eyed Juncos have joyfully entered the limelight, and flocks of Pine Siskins are around but not in the nets.   In the last few weeks of migration, we also banded many Golden-crowned and Ruby-crowned Kinglets, Myrtle Warblers (or butter-butts), Palm Warblers and leftover Black-throated Blue Warblers along with exciting birds like Lincoln’s Sparrow,  Field Sparrow, White-crowned Sparrow, our first Blackpoll Warbler of the season, a  Savannah Sparrow, a Saw-whet Owl (during the day!) and an exceptionally magnificent WOODCOCK!!  We often flush American Woodcocks from the hedgerows in the pre-dawn moments, but we’ve never captured one until now.  There’s never a dull moment at the Rushton banding station.

On Friday after Sandy, we braved the frigid air to band over 50 birds of 16 species including a handsome Fox Sparrow (always the last of the winter sparrows to show up) and ANOTHER AMERICAN WOODCOCK.  This bird was aged as an adult male as evidenced by the shorter bill length and stubbier wing in addition to a narrower p10 in relation to the female.   P10 is the tenth and outermost primary flight feather, which is stiff and narrow in male woodcocks to give their flight the nice twittering sound that gets the lady woodcocks excited during their elaborate aerial courtship displays!  Just as fabulous to see up close was the prehensile bill tip that these birds use to feel and grasp their food (earthworms) while probing in the mud.  With big beady eyes to see in the dark and precisely camouflaged leaf-like coloring this bird is a spectacular, crepuscular and cryptic beauty!

American Birding Association Visits Rushton Owls on a Record Breaking Night!

On the last Saturday of October, we were thrilled to welcome to Rushton Adrian Binn’s and Deb Beer’s distinguished guests, Jeffrey and Liz Gordon,  the passionate President and “First Lady” of the American Birding Association (ABA).  The ABA is a nationally recognized non-profit whose mission is to inspire all people to enjoy and protect wild birds through birding and consequently habitat conservation.  Check out the ABA website to learn more about this great organization’s mission.

On that special Saturday, October 27th, around 11:30 pm your fabulous Rushton banding crew,  accompanied by the American Birding Association, elatedly banded our 92nd new Northern Saw-whet Owl (NSWO) of 2012, surpassing the 2010 season record of 89 new NSWOs!  At that time in 2010 we had only just begun banding on October 28th after we got this brand new owl banding station up and running.  Even if we had been banding the entire month of October in 2010, we still would not have seen the numbers we are seeing this year because 2010 was a more typical fall born from food scarcity in the north with migration of adults and young peaking around October 31st.   This year the peak has occurred much earlier than usual with an influx of fat babies spilling south ahead of their elders after a northern summer of luxury and abundance.  While the young owls have been flooding through Rushton for all of October, the adults have only just arrived in very small numbers.

In addition to these 92 “New” Saw-whet Owls never before banded (now 120 as of last night, November 4) , we also catch owls from other banding stations, Foreign Recaptures, like the young owl banded in Ellenville, NY that ended up at Rushton this fall after flying 130 miles south in a week or so.  In addition, we catch some of our  own banded owls, Retraps.  Retraps can linger for days or weeks at Rushton, eating the tasty voles and mice that thrive in the farm’s pesticide-free environment (Thank you, Farmer Fred!).  We also catch local Eastern Screech Owls.  Counting Screeches, Retraps and Foreign Recoveries, we caught more than 20 additional owls so far this year.

One of our owls banded at Rushton on  November 1, 2011, was caught on the north shore of Lake Ontario in Canada on October 16th this year.  That bird is over three years old and obviously taking its time traveling back south to Rushton this fall!

As for the Northern Saw-whet Owl public banding schedule, we are banding most nights with Thursday, Friday and Saturday being public.   Please reference the last blog entry , which has all the information you need to know about visiting Saw-whet Owl banding, and  email Lisa Kiziuk ( lkr@wctrust.org) to make a reservation.  

Doris McGovern, Rushton’s Master Bird Bander, spelled  out our mission beautifully:

“Our goal is to contribute data to the continent wide Saw-whet Owl banding network.  We report owl data to the USGS where it becomes part of a national data base for researchers.  We currently mentor college grads who need research skills, such as bird banding.  We share our knowledge of owl biology with school groups, home schoolers, scouts, CSA members, local bird clubs and interested adults.”
“We want you to be proud of all that your WCT owl banding team does while you are comfy in your soft, warm bed and we are shivering in a cold, drafty barn with our fingers bleeding from the sharp talons of those cute little Saw-whets you love so much.   Are you drinking hot cocoa?  We love hot anything,” tweets Doris McGovern.

PA Young Birders and Owls

The PA Young Birder (PAYB) Owl Night on October 19th was a hit!  Over 60 people (including 35 children) enjoyed the night through an owl’s point-of-view and learned about the science behind bird banding.  Eight Northern Saw-whet Owls bravely presented themselves to the crowd for banding and photographing and “oohing and awing”.  Other highlights of the night included creating masterful owl art with Adrian Binns, telescopic moon gazing with Deb Beer, and enchanting (albeit muddy) night hikes with me, Blake Goll.

Giving Thanks for the Owls of 2011

December 9, 2011 By Communications Team

Northern Saw-whet Owl perching on a tree branch

Our banding station is officially closed for the year (both songbirds and owls), which means it’s time for us banders to get back in the office and put our lives (and our desks) back together again!  We tried a few more times for owls around Thanksgiving when we heard that other banding stations both north and south of us were getting more owls.  King’s Gap  in Cumberland County (one of Scott Weidensaul’s banding stations northwest of us) caught 5 new Saw-whets on November 23rd!  On November 21st Glenn Proudfoot, another owl bander in Poughkeepsie, NY, actually hand-plucked one female Saw-whet off of a rope that was holding one of his net poles up!   She was not in the net and was totally free to fly away at any moment if she wished.  This is not so unusual considering the surprisingly calm  nature of some of these individuals.  What is most notable about this story is that he named the owl Marsha Mellow!  🙂

We opened our nets the night after with high hopes and caught nothing…although we did see a flying squirrel spying on us and hear Saw-whet Owls calling in the woods. We suspect there are a couple of owls  that decided to overwinter in our area, and they have grown weary of investigating the invisible, loud-mouthed male that sings for hours on end during some nights, in the midst of giant spider webs!

Coincidentally, the very last Saw-whet Owl we captured this year (on November 19th) was the very first owl we caught this year (October 21st).   We have no way of knowing if this young female (band # 37) was here the entire time or if she wandered many miles away and came back, which is very likely considering the nomadic nature of these woodland elves in winter (as discussed in my last blog post).  In any case, it certainly seems that #37  is at least using Rushton as her home base this winter.  Don’t forget, however, that these spritely owls have the ability to travel far and wide if they want to; this fall, one young female was reported to have traveled from a banding station in Ontario to one in Alabama in just one month!

Our Saw-whet Owl total for the season is just 34, which is a comparable low to other banding stations in the east.  The grande total ( a new all time low) for all three of Scott Weidensaul’s PA stations (King’s Gap, Hidden Valley, and Small Valley) is 116 as of November 30th; the previous low total for his stations was 201 in 2006.  Last year, he banded over 340 owls across all 3 sites, and we banded 91  owls here at Rushton Woods Preserve.  That was one of the best years so far.

I have not heard a definitive answer to the question of why there were so few owls showing up at eastern banding stations this year, although most banders agree that the resources up north were probably insufficient during the owls’ breeding season this year.  The majority of banding stations banded more adult   and less Hatch Year owls (birds born this summer) this year than previous years. This could be an indication that there weren’t many baby owls this year as a result of low breeding success; either the parents did not have the resources to have many babies, there was high juvenile mortality caused by lack of food or it was a combination of both scenarios.  In certain previous years, lower numbers of Saw-whets traveling south actually meant that the resources up north were abundant, thus diminishing the need to migrate in winter.  However, the low totals we saw this year coupled with the lower ratio of Hatch Years to adults is a sure sign that the little fuzzballs had a rough summer.

Even the  Saw-whets’ plumage revealed evidence of stress.  Just to give you some background,  we age birds based on their species-specific molt patterns, with particular emphasis on the flight feathers.  Molting requires a great deal of energy and nutrients, so a bird born this year (Hatch Year-HY) will not usually carry out a complete molt; it may molt all of its body feathers and only some of its flight feathers.  The “unmolted”  feathers are called retained juvenile feathers and usually appear dingier, lighter in color and more worn than the fresh molted feathers.  We think of these retained juvenile feathers as the “cheap Kmart feathers”!   The boundaries between tracts of new and old feathers are called molt limits.

A Second Year Saw-whet Owl. Notice the "cheap Kmart" feathers in the middle of the wing contrasting with the dark, new outer and inner flight feathers.

An HY Saw-whet Owl will usually show no molt limit because they do not replace any of their juvenile feathers in their first fall.  They have too many other things to be worrying about, like learning to hunt and stay alive!  Therefore, an HY Saw-whet has all uniformly “trashy” looking flight feathers.  A Second Year (SY) owl usually shows a molt pattern of several outermost primaries and innermost  secondaries replaced; these feathers look darker and have less nicks than all the flight feathers in between.  However, this year banders were seeing more SY birds with only a few outermost primaries replaced and no inner secondary feathers replaced.  Such suspended flight feather molt is most likely another result of lack of adequate resources on the northern breeding grounds where the bird molted after mating.

Ageing Saw-whet Owls is sometimes easier with a blacklight. Under a blacklight, the new feathers show up bright pink because of a special pigment they contain. This is a typical Second Year molt pattern, where an outer primary and some inner secondaries are replaced. The white feathers in between are older and have thus lost the pigment.

We are certainly thankful for the few beautiful owls that Mother Nature did send our way this year, and we wish them the best of luck as they survive the winter and return to their breeding grounds that will hopefully present better conditions in the new year!  These owls are truly amazing little creatures, more adorable than the cutest stuffed animal, as whimsical as a fairy tale gnome, as silent and elusive in flight as the Luna moth, as mellow and approachable as a garden toad, more formidable a hunter than a wild cat, and at times as ferocious as a miniature fire-breathing dragon!

You can’t help but love them and be captivated by their steadfast, yellow-eyed gaze.   I find myself wishing I knew what she knows, yearning to  see the wild places she has seen, longing for the untamed solitude she has experienced, craving to fly on wings of silence through the night, and wanting to be close to her as a friend.    She embodies nature at its finest.

Thank you to all who came out to our bird banding station this year, bringing interest, enthusiasm, and support.  We are thrilled to be able to connect people to the  nature that makes us whole, feeds our soul, and renews the bonds between us and the land from which we so easily become isolated.

A special thanks to our dedicated group of PA Young Birders who have been regularly attending our monthly meetings!  We had fun at last month’s meeting learning about cavity nesting birds, looking for old bird nests in Rushton Woods Preserve and drawing our favorite cavity nesting birds.  The Jr. Birders even learned how to use power tools to help make a bluebird box that the Trust will install on one of our properties!

Don’t miss this month’s meeting, “A Winter Bird Count”, on Saturday, December 17th from 9 AM – 1PM.  PA Young Birders, ages 8-12, will meet at the Willistown Conservation Trust headquarters (925 Providence Road, Newtown Square, PA) where we will learn how to identify wonderful winter birds.  Then we’ll  learn about the honored tradition of the Christmas Bird Count before heading out into the field with our binoculars to see what we can see!  We’ll return to the office for a Tally Rally of the birds we counted, while enjoying hot pizza and cocoa by the fire.  Be sure to wear lots of holiday cheer and many warm layers!  Please RSVP to Lisa Kiziuk (lkr@wctrust.org).

The Christmas Bird Count began in 1900 by a man, named Frank Chapman, who proposed counting the birds instead of shooting them.   Unfortunately, it had been a holiday sport for local farmers and residents to shoot as many birds as they could until sensible people, like Frank, began showing concern about alarming declines in bird populations.  Today, the Christmas Bird Count is the largest wildlife survey in the world.

You don’t have to be a kid to participate in the spirited tradition of the Christmas bird Count!  You also don’t need to be an expert birder;  since there is a specific protocol and the data is very important, beginner birders will be placed in a team with at least one other experienced birder.   The Christmas Bird Count season is December 14 through January 5 each year.  To learn more about this elaborate citizen science project and to find participating birders near you, go to Audubon’s website.   It’s a great way to meet new people, build your birding skills, experience nature in winter and contribute to the conservation of birds during this season of giving.   Plus, hot chocolate tastes better than ever after hours of winter bird counting!

Speaking of searching for birds in winter, be sure to keep your eye out for SNOWY OWLS!!!  Like the Northern Saw-whet Owl, the Snowy Owl is an irruptive species that is closely tied to the rodent population on their northern  breeding grounds, especially lemmings.  This is an irruption year for Snowy Owls, which means that the dramatic decrease in lemmings is drawing them south from their usual Arctic Tundra territories in search of food. So far this winter, there have been over 100 reports of these Arctic ghosts in Wisconsin and other midwestern states and even one in Hawaii!  Just over a week ago, a Snowy Owl was reported by several individuals east of Allentown on the PA/NJ border!

These magnificent rare beauties are coming our way.  Stay tuned for when one shows up near us….you can bet the bird nerds, like me, here at the Willistown Conservation Trust will ‘stop, drop, and bird’ at the first local report of a Snowy Owl!  The last time a Snowy Owl irruption of this magnitude occured was in 2006.  Interestingly enough, 2006 was also the runner-up to this year in setting the record low for numbers of Saw-whet Owls traveling south from their northern haunts.  Here’s a Google Map of Snowy Owl sightings so far this year, and click here to read a recent article in the Wisconsin State Journal about the 2011 Snowy Owl irruption.

Songbird Banding Comes to a Close and Saw-whet Owl Movement is Sluggish

November 17, 2011 By Communications Team

Migrant shorebirds at the Delaware Bay (Redknots, Ruddy Turnstone, Sanderling, Dunlin). By Blake Goll

“These were, perhaps, the original poetry…

…in tune with the lift and fall of the seasons,

returning from nowhere,

or from  an unknown terrain

which must consequently exist….

…They needed, for no obvious reason, two worlds

in which to feed and breed,

so they needed a capacity for sustained flight,

a fine orientation,

an ability to sleep on the wing

an instinct for form and its rhythms

as each took its turn to cut the wind.”

-Adapted from “First Poetry”, by Moya Cannon, a lovely Irish poet who visited our Rushton banding station this year.

Well folks, it’s about that time…time to admit that the thrilling movement of fall songbird migrants is coming to a close as Old Man Winter looms closer.  Last week, our nets produced very few birds (around 30 each day), the majority of species being White-throated Sparrows and Dark-eyed Juncos here to stay for the winter.  We also banded many year-round residents like Blue Jays, Northern Cardinals, Carolina Chickadees, and Tufted Titmice.  As usual, these classics were crowd-pleasers, especially for the 15  Girl Scouts who came out to Rushton Woods Preserve last Tuesday to learn about birds and earn their honorary Wildlife Badges!  The 4th grade girls eagerly learned how to use binoculars, practiced identifying birds by sight and sound, studied the intricate structure of bird feathers, and kept nature journals of their avian field sketches.  They were quite the little naturalists!

Of most interest last week, in terms of the songbird catch, were a lovely Fox Sparrow and a dashing Red-bellied Woodpecker.  The Red-bellied Woodpecker was “nothing special to us”, but our guest bird bander, Emily Thomas, from the Allegheny National Forest of PA was absolutely ecstatic when she heard he was in the net!  She sprinted to the net so fast, she said she pulled a muscle!  The Red-bellied was one of the few birds she had not seen in the hand in her 7 years of banding because they are not common farther north and in higher elevations, like the Appalachian Mountains.  Click here to see the range of our Red-bellied Woodpecker.   Never take our common beauties for granted; what is common to us might be extraordinary for someone else!  I, myself, remember longing for the familiar Northern Cardinals when I was bird banding in the Pacific Northwest two summers ago.

Emily Thomas was visiting our neck of the woods to speak at The Delaware Valley Ornithological Club (DVOC) and The Birding Club of Delaware County (BCDC) about her interesting graduate research on the effects of oil and gas development on songbird habitat and communities.  By the way, both of these prestigious bird clubs are welcoming communities in which to become involved if you are an avid birder, want to cultivate your beginner birding skills or want to make new birding buddies!  Both clubs hold interesting birding field trips and have monthly meetings and frequent distinguished speakers.

In a nut shell, what Emily found from her research is that the habitat fragmentation in the Allegheny National Forest from Devonian shale shallow wells actually increases bird species richness (the number of different species).  This is because forest clearings from well pads and service roads allow more understory and small-gap loving species (like Indigo Buntings and Cedar Waxwings, respectively) to move in alongside some of the remaining closed canopy nesters (like Blackburnian Warblers) that were there before.  However, such fragmentation does result in the loss of  some  specialist species (ie. closed canopy nesters like Magnolia Warblers) that are unique to that Northern hardwood habitat.  A lot of the new species that move in after oil and gas development are generalists like American Robins.  In the end, Emily projected her Devonian shale conclusions on Marcellus shale, predicting that the effects of Marcellus fragmentation will actually be less because one deep Marcellus shale well pad can access resources that would require many shallow Devonian pads.  However, the habitat footprint for a given Marcellus well pad will be larger than that of any individual shallow Devonian well.  It’s all very complicated!  For more information on oil and gas development in PA go to http://extension.psu.edu/naturalgas or  http://www.dep.state.pa.us/dep/deputate/minres/oilgas/oilgas.htm .

Did you know that baby ticks are out and about?  I didn’t even know what a baby tick looked like until last week when we saw little orange bumps on some of our birds, around their eyes and in their ears!  Since we did not get a picture of the ticks, go to Hilton Pond’s website and scroll down for a nice (or not so nice!) view of a cluster of ticks under a jay’s eye.  We found these exact same clusters on our Blue Jay’s eye as well as in the ear of other species like White-throated Sparrows.  Apparentl,  they are called seed ticks and will go through several more stages of development before reaching maturity.  Yuck!

As for the Northern Saw-whet Owls (NSWO), we are getting shut out left and right.  Last year, we banded a total of 24 nights for 91 NSWO.  This past Saturday (11/12) was our 24th night this year, and we’re still at only 34 NSWO plus 2 Eastern Screech Owls.  As of November 10th, Scott Weidensaul was at 86 owls across his 3 sites (compared to 336 last year to date), which is well below his 10-year average for the date of 187.   All of these warm, moonlit nights with South winds are not great for Saw-whet movement.  Other owl banding stations, like the Ned Smith Center for Nature and Art, find this trend to be true as well; north winds generate more southbound owl movement.  In fact, some other owl banders have been speculating that the role of wind direction in local movements of these tiny owls  is significant enough to conclude that they are not a truly migratory species, but rather a somewhat nomadic species with opportunistic migration.  It’s never black and white in nature, which is what makes banding so interesting and exciting!

On a related note, the big news last week was our nomad number 0904-08744, which found one of Scott Weidensaul’s (famous author and naturalist) nets at Hidden Valley on November 6 after having been banded by us at Rushton on Halloween.  I guess Scott’s Valley isn’t so hidden after all!  The Saw-whet Owl was a Hatching Year female (born this summer).   This recapture shows that she wandered about 60 miles Northwest to Hidden Valley from Rushton in 6 nights.  This same northbound wandering during migration occured last year when another Saw-whet we banded on November 9 was captured 5 nights later, on November 14th,  at another one of Scott Weidensaul’s owl banding stations called Small Valley (in the same general vicinity of Hidden Valley).  That’s two documented cases of northward wanderings at the tail end of “southbound  migration”!  This record is  also remarkable because Scott encouraged the creation of our owl banding station when Lisa Kiziuk volunteered at Hidden Valley in the 2009 season.   Talk about a full circle!  Check out the Ned Smith Center’s Owl Research page for more information on Saw-whet Owl research.

Young Ruby-throated Hummingbird

While we are on the topic of Scott Weidensaul’s research, did you know that you should be keeping at least one hummer feeder filled and available at least through Thanksgiving?   If you’ve put away your feeder already, consider putting it back up and you might get a western vagrant!  Scott is one of only about 200 hummingbird banders in the country studying newly evolving migration routes of western hummingbirds.

Rufous Hummingbird (derived from Google Images)

Traditionally, only the Ruby-throated Hummingbird was found east of the Great Plains, departing in September and wintering in the tropics. However, in recent years, almost a dozen species of western hummingbirds have been showing up in the East and Southeast in autumn and winter (including Eastern PA!).  Hummingbird banders studying this emerging phenomenon are finding that  most of these vagabonds are Rufous Hummers that breed in the Rockies, Alaska, and the Pacific Northwest and typically winter in Mexico.  However, changes in the landscape coupled with the warmer winters of the past century have made the east hospitable; those that survive and return to breeding grounds are passing on these “vagrant” genes that were once unfavorable, resulting in this  rapid evolution of a new migratory route and wintering area for these birds.

Most homeowners take down their feeders when the last Rubys leave in September, but these Westerners don’t appear until October, November, or even December. Put that feeder back up if you want a chance at an early little Christmas gift wrapped in iridescent feathers! After Oct 15th, you should contact Scott Weidensaul scottweidensaul@verizon.net  if you are sure you have an overwintering western hummingbird.  He or a fellow bander will come to your home, capture and band the bird, and release it to continue migration.  The results can be spectacular!  For example,  in January  2010 a Rufous was banded in Tallahassee, FL and was recaptured 6 months later in Chenega Bay, Alaska! This information is vital to understanding how these migration routes are evolving.

Most people find it astonishing that hummingbirds can survive cold winter weather.  Western hummers are actually very hardy  because they are accustomed to nesting near timber line at high elevations where they can tolerate sub-zero temperatures if need be.  These amazing birds can go into deep hibernation-like torpor on cold nights (rubys can only do this to a small extent) during which their body temperature is reduced from 102 F to just 54 F!  As for finding enough to eat in cold weather, hummers can find dormant insects and  spiders or cold weather active midges.  The birds have also been known to drink tree sap from sapsucker wells!  Visit Scott’s website to learn more about this fascinating western hummingbird research.

Schedule for the Rest of the Banding Season:  Songbird banding is closed for the season, and this Friday and Saturday will be our next owl banding nights.  As always, please sign up with Lisa Kiziuk, lkr@wctrust.org, to reserve an owl banding spot!  We have not had a good night since November 5th, when we got 7 owls.  Since then, we have only been getting one, two, or no owls each night.   We’ve also been getting the same owls that we banded several nights before, like Feisty 54.   We captured Feisty 54 four times so far this season: first on November 2 and twice in one night on November 11!  This ferocious older female may still be haunting Rushton because, although we aren’t catching any owls these nights, we keep hearing Saw-whet calls that we suspect are coming from Feisty 54.  Maybe she scared everyone else away!  In any case, we are hoping for a few more owls before we shut down for the season (many northern stations have already closed).  Even if we don’t get any new owls for audiences this weekend, there is a good chance of recapturing good old Feisty 54!  I think she is starting to enjoy the attention.  And I’ve also noticed that the human camaraderie is at its best on owl-less nights.

Never a dull moment here in the woods,

P.S.  The last PA Young Birder meeting on November 4th was a big success… with over 50 kids of all ages and no owls!  Luckily, there were so many other fun activities going on (owl art, campfire and s’mores, night hikes, owl seek and find, and owl slideshows) that I don’t think the kids remembered that we were even trying to catch owls!

The next PA Young Birder Meeting, “My Nest is Best,”  is this Saturday November 19 from 9:30-11am at Rushton Woods Preserve.  The Jr. Birders (ages 8-12) will learn about bird architecture and the many different types of nests that birds construct in various habitats.  The children will assist with nest box installation for the Trust and will hunt for real cavities used by birds in the woods of Rushton.  Please RSVP to Lisa Kiziuk, lkr@wctrust.org.
