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.

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.
Happy New Year!  I thought I’d send a little feathered beauty your way and some thought-provoking quotes to start off your 2015.
On why you should bird more in 2015:
“Looking at birds really takes away sadness in a lot of us,” said a woman featured in Jeffrey Kimball’s film (The Central Park Effect), a breast-cancer sufferer who ushers fellow birders on ambling tours of the park.
“It was one of the rare times in an adult’s life when the world suddenly seems more magical rather than less,” says writer Jonathan Franzen, a self-proclaimed “born-again bird watcher,” of the first time he went birding.
On why you should take a child outside often this year:
“If a child is to keep alive his inborn sense of wonder, he needs the companionship of at least one adult who can share it, rediscovering with him the joy, excitement, and mystery of the world we live in.”

On why you should watch less TV this year:
“There are some who can live without wild things and some who cannot.  For us in the minority the opportunity to see geese is more important than television” …Aldo Leopold (Sand County Almanac)

–Anonymous
On why you should strive to give back to nature this year:
“In every walk with nature, one receives far more than he seeks.”  -John Muir
“In all of nature there is something of the marvelous.” -Aristotle
“I speak for the trees, for the trees have no tongues.”  – The Lorax
“It is in the wild places, where the edge of the earth meets the corners of the sky, the human spirit is fed.”    ~Art Wolfe
“If future generations are to remember us with gratitude rather than contempt, we must leave them a glimpse of the world as it was in the beginning, not just after we got through with it.” -President Lyndon B. Johnson
Tread lightly this year, get outside, go birding, learn all you can about nature and be a participant in conservation!
There’s a lot going on in the woods,

Happy Owl-o-Ween!

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!

They wanted me to share a preview of the performance here.  We humans say that it sounds like a “toot”, but to their more refined ears, it’s much more than that.
Register for the Junior Birder Owl Banding Night, November 15th, by emailing me, Blake Goll (bhg@wctrust.org). Space is limited.
Hope to see you there!  Trick-or-Toot!!

The Spirit of Autumn

________________________________________________________

It is a beautiful crisp October day, with the changing leaves standing out in stark contrast against the somber, gray sky.  As I stand in the driveway of the picturesque office of Willistown Conservation Trust, I am enchanted by the feathered feeding frenzy!  The trees are alive with rustling leaves that magically morph into bustling birds, flitting here and there to the rhythm of the Autumn spirit.  Two Blackpoll Warblers wizz by my head in an animated chase, enlivened by the crisp air in this moment and forgetting about the many more miles they have to go before their winter sojourn in the tropics.

Many more warblers dance around in the upper reaches of the maple and hickory trees.  The commotion of these strangers in the neighborhood stirs up the curious residents- the chickadees and titmice- who join the feeding flock. Perhaps the migrant flock found the resident chickadees and titmice first since these are the ones to trust when it comes to knowing where the best food sources are and where the predators are.  Migrant flocks of birds are quite cunning like that.  They must be. Their lives depend on it.
Tap. Tap. Tap tap-tap tap. Tap.  My ears lead my eager eyes to a medium-sized woodpecker skirting its way up a dead tree trunk.  The October shadows obscure the bird’s coloring from my view.  Could it be a Yellow-bellied Sapsucker!?  There have been many reports of these handsome migrants in the area!

Now my eyes are drawn to the Rudbeckia triloba (or Brown-eyed Susan) in the front bed of the office.  Several flowers are nodding toward the earth and others bouncing up and down wildly under the weight of wild canaries!  These are the resident goldfinches with their young of the year, voraciously harvesting the seeds of this wonderful native plant.  I look up to my right where I see more movement in the willowy River birch from which a feeder hangs.  More goldfinches are pecking at the birch catkins to extract nutritious seeds even as the bird feeder sways enticingly beneath them, filled with hulled sunflower seeds.  You just can’t beat the opulent menu that nature offers for birds this time of year!

Looking out across the Trust’s native wildflower meadow, I see more old seed heads from the retired perennials bobbing up and down and small figures swooping around the golden grasses and diving in amongst the gray and amber stalks.  I don’t grab my binoculars because I want to experience the whole of this pulse, rather than pick out the individual birds in this moment.  I know there are mixed warblers, sparrows and more goldfinches out there in the meadow, and I am content to be wrapped up in the spirit of Autumn with child-like glee.

And I think to myself, what a wonderful landscape for these deserving creatures to relish.  Our meadow will be mowed in early spring to keep the woody growth and invasive plants at bay, but for now its unmowed glory is a paradise providing shelter, seeds, insects and berries for countless small animals and birds.  The insects themselves can find solace here; who knows how many praying mantis egg cases, underground bee burrows and silken cocoons are hidden safely amongst the leaf litter, ready to emerge in the new year and pass on their small but significant life force.

As I’m again enjoying the goldfinches feasting in the birch, a lovely Hermit Thrush silently enters the scene like an apparition and perches gracefully on a branch, gently and diagnostically bobbing its fox-red tail up and down to that same infectious pulse that seems to be rippling through this large flock of migrants – and now my heart.
This is the excitement that can come of a typical cloudy October day, when one simply tunes into the cycles of nature.  Someone once told me,”never despise the day of ordinary things.”  I say, when you invite birds and nature into your daily routine, the ordinary day becomes rare.

All of us banders at the Rushton banding station know this to be true.  This fall season has been an exciting one with great species diversity (20 species one day!) and satisfactory numbers of migrants.  The most we had in one day were 83 birds back in September when the Gray Catbirds were still going strong.
Now the catbird flow has tapered off, and the sparrows have entered the stage in full force including Lincoln’s, Swamp, Song, White-throated and even a Savannah!  Field sparrows passed through earlier this fall.
The stream of warblers has also been slowing down, although last week we did catch a Magnolia Warbler, Black-and-white Warbler , Blackpoll Warbler and the usual Common Yellowthroats.  This week’s warblers included Black-throated Blue, Magnolia, American Redstart and first of the season Yellow-rumped (Myrtle).
Wood thrushes have all passed through and have been replaced by Swainson’s Thrush, a few Gray-cheeked Thrush and tons of American Robins.  We are expecting Hermit Thrushes, oodles of kinglets and loads more White-throated Sparrows to hop into our nets soon, followed by juncos and a Fox Sparrow or two to round out the season.
Noteworthy flyovers have included two regal Bald Eagles and a very mysterious Common Raven flying Southwest as it issued its guttural croaking call.  Blue- headed Vireos serenaded us with their slow, playful song from the tops of the trees today.  In the predawn, Bobolinks were heard over the farm on September 30th and an American Woodcock was heard one morning in mid-October.  The Great Horned Owl sang to us many mornings during net setup.
People visitors, eager to see and learn about these migrating wonders, have been flocking to the banding station as usual.   Visitors included the Birding Club of Delaware County, representatives from the Academy of Natural Sciences, businesses, Junior Birders, elementary school students and Universities like Villanova and UPenn.  We even have a UPenn student analyzing stopover ecology data this season.  This pertains to the timing and rate of weight gain in migrants during their stay at Rushton before continuing their migratory journeys.  This type of data is revealed by same-season recaptures of birds.
Enjoy the following photo journal of the season highlights so far.  Pretend you are birding!  Hope to see you out there at Rushton (Tuesday and Thursday mornings through the end of October).
There’s a lot going on in the woods,
Blake

Gray Catbird at Rushton in September. Notice the noticeably browner feathers on the front of the wings compared to the grayer ones further back? The brown feathers are juvenal and the gray ones are adult, so we know this bird was hatched this year.  This contrast in ages of feathers is what we call a molt limit.  This is one way to age birds in the hand (and in the field).
