This Year The WILLISTOWN CONSERVATION TRUST Received A GENEROUS NATIONAL AUDUBON AND TOYOTA “TOGETHER GREEN INNOVATION GRANT” TO RESTORE AND PROMOTE SHRUB HABITAT FOR BIRDS

One of only 40 nationwide Together Green 2012 grant recipients, the Willistown Conservation Trust, in partnership with Audubon PA and Valley Forge Audubon, received  $20,500 from National Audubon and Toyota’s Together Green Innovation Grant program!  We are proud and thankful to have received this prestigious award and will use it to help preserve and raise awareness of Early Successional Scrub/Shrub Habitat (ESSH) for the birds.

ESSH is that low shrub habitat that we have all seen but may not have been able to name.  It includes mostly shrubs , a few small trees, and some wildflowers and grasses.  This is the type of habitat that occurs or succeeds after a grassy area has been unmowed for several years.  The beauty of these shrub areas may be difficult to see until you realize the immense value this threatened habitat holds for young birds and other wildlife.

Here are some examples of Early Successional Shrub Habitats:

In order to promote this under appreciated and often misunderstood habitat, we are in the process of creating one of Pennsylvania’s first multi-site models for ESSH!   Our three demonstration sites in the WCT program area will include an area in Ridley Creek State Park, our own Ashbridge Preserve and Rushton Woods Preserve; these sites will show landowners the ecological value of ESSH and the applicability to managing and preserving ESSH on their own properties.  The model sites with varying degrees of management will show landowners that promoting ESSH on their land can be as simple as just not clearing a shrubby area or can involve planting native shrubs and managing tree growth.  Work Day activities at the demonstration sites will include some removal of invasive plants, the planting of native shrubs (selected to provide the structure and food sources needed by migrant and nesting birds), and fencing plots for deer protection.

During this project, we will not be placing major emphasis on the removal of vines and invasive plants because it is a controversial subject.  New findings suggest that heavily invaded areas are in fact quite stable and capable of carrying out the same ecosystem services as pristine environments; these human influenced natural areas can be allowed to provide good habitat for birds and wildlife rather than be “torn out in an expensive and fruitless attempt to return native vegetation dominance” in an “unceasing tide of change,”  as suggested in “The New Normal”, an interesting article in Conservation magazine.

This shrubby habitat may include invasive plants and may look “messy”, but it is stable and provides great habitat structure for birds.  Clearing such an area would not only eliminate habitat but would also destabilize the streamside habitat, resulting in erosion and sediment deposition in the stream.

In addition to work days for our ESSH project, there will be a series of fun and educational workshops offered in the spring for landowners and anyone interested, which will feature interactive tours of these ESSH demonstration sites, mini hikes, bird banding and bird surveying (which will be crucial to the monitoring of these  demonstration sites).   Ultimately, what we really want  is to shift people’s suburban mentality to a mindset that allows them to see the natural and ecological beauty of Early Successional Scrub Habitat.  We want landowners to have a strong enough connection to, understanding of, and sense of responsibility to nature that they think twice (particularly about birds) before clearing shrubby areas on their property or that if they do clear they go about it in a sensitive way (in stages) and are prepared to replant with natives.

With lawns totaling 1.2 million acres in the U.S. and 21 million acres of natural land being lost to residential development each decade (according to the Cornell Lab of Ornithology),  it’s time for all of us who value wildlife and biodiversity to begin viewing our properties as habitats.  If everyone shared just a corner of their perfectly manicured (and biologically barren) lawn to natural habitat, whether it be an unmowed field, wildflower meadow or shrub area, think of all the extra room there would be for wildlife that we and our posterity could enjoy!

This “backyard as habitat” movement has already begun to take root as evidenced by bestsellers like “Bringing Nature Home” by Doug Tallamy and “Noah’s Garden” by Sara Stein.  The Cornell Lab of Ornithology even has a cool new citizen science project, called YardMap, that encourages homeowners to map their yards in a network of people dedicated to providing habitat for birds in their yards.  Each property can make a difference, and the more properties that participate the easier it becomes for birds to move between these patches of habitat.

Early Successional Scrub Habitat is a great place to start in this “backyard as habitat” movement because ESSH is valuable to birds even in small, patchy distributions like yards.  Unlike grassland dependent species, like Eastern Meadowlarks, which require acres upon acres of contiguous grassland habitat,  most shrub-associated birds, like Common Yellowthroats and Gray Catbirds, are typically not sensitive to patch size.  Therefore, even efforts on individual properties can affect local breeding populations.

In addition to nesting habitat, ESSH offers crucial cover and food sources for birds throughout the year, including baby birds trying to survive their first and most vulnerable year of life.  It’s a fact that over 50% of baby birds do not make it through their first year of life.  In a recent telemetry study by the Cornell Lab of Ornithology, scientists found that even birds like Wood Thrush and Ovenbird that have long been considered emblematic of undisturbed mature forests will head straight for brushy tangles that ESSH offers after leaving their nests.  These thickets offer more protection than open woods from predators like hawks, snakes and chipmunks.

We see this phenomenon at Rushton where we band in the shrubby hedgerow during spring and fall migration.  Most of the birds we capture in the shrubs in early fall are hatching year birds (baby birds born that summer) of all different species including the woodland nesting birds.  Many of these young woodland birds are even recaptured in the hedgerows in fall after we banded them as “fresh-out-of-the-nest” babies this summer in the woods, which proves this species-wide affinity in hatching year birds for ESSH.  These recaptured birds of two habitats have included Wood Thrush, Ovenbird, Downy Woodpecker, Common Yellowthroat, Veery, and even a Kentucky Warbler.  Hence, banding also reveals the nuanced story that telemetry has begun to reveal-that just because a bird breeds in one specific habitat does not mean that it doesn’t need other habitats for the other parts of its life.

In the spring and fall, many exhausted migrants of all ages also seek and value that “other habitat”, ESSH, for food and shelter.  Through banding we have discovered that many young and some adult birds of all species, no matter what their breeding habitat preference, see Rushton’s shrubby habitat from above and decide to touch down for refueling .  Birds of all species seem to have a search image, whether learned or genetic, for these types of shrubby areas during migration.  They know the shrubs are teeming with berries and insects and that they will find rest for their weary wings in the thick protective undergrowth.

Migrant Saw whet Owls also love these shrubby areas for the healthy population of mice and voles they often support and for the dense thickets the shrubs offer for secretive roosting during the day.

Here are some migrant birds that enjoyed their stay at Rushon’s Early Successional Habitat this fall, whether they dined on insects or berries or rodents!

Bird populations as a whole are declining, and migration is so fraught with peril that bird mortality rates are 15 times higher during migration.   During migration and throughout their lives, birds are faced with habitat loss and other human threats like pesticides, toxins, harmful fishing practices, free-roaming cats, and  communication towers and wind farms with which they often collide.  Comparisons of spring radar records from 1960s to those from the 1980s show a sobering 50% decline of migratory activity on favorable weather days.

Therefore, we are excited to do what we can for the birds by  promoting Early Successional Scrub Habitat, which in itself is threatened in Pennsylvania.  Historically, ESSH was much more prevalent in forest gaps in PA that were routinely created by fire, storms, Native Americans, and beavers.  Now fire is suppressed and beavers have been wiped out of most areas from trapping.  In addition, many people are clearing these shrubby areas with the misconception that they are junky “unnatural areas.”  Other landowners would rather let the shrub habitat succeed into forest, which is sometimes perceived as more valuable, ecologically and economically.

With the Together Green Innovation Grant, the Trust hopes to encourage landowners to preserve and even help create ESSH for the benefit of our natural heritage and the birds that so desperately need our help.   It’s time to embrace those wild, unkempt areas on our properties and see the beauty in the great biodiversity such places can hold.  These are places full of life on our properties that, instead of getting frustrated with, we should be getting excited about and treasuring for the hope and wonder it holds for us and for our children.

Another major purpose of this grant project is to connect people to nature who have not previously been a part of the conservation movement.  On Election Day this fall, we held our first Together Green work day at Rushton Woods Preserve and Farm during  which about 20 students, ranging in age from 3rd to 5th grade, worked alongside a handful of adults to plant 100 native shrubs in our ESSH demonstration area.  These urban students were from the Melton Arts and Education Community Center of West Chester where I first taught them about birds and the importance of habitat a couple of weeks ago during an after school session.  The workday was an excellent opportunity for the children to show us that they not only listened but cared deeply about the topic.

All of the tensions and hot air surrounding the imminent election dissipated as the adults were blown away by the students’ single-mindedness and earnest compassion for the environment. The students first visited the songbird banding station  where they were delighted to see familiar birds up close like the Blue Jay and Cardinal.  Some students, not normally known for having a gentle touch, softly held the birds before releasing them and breathed, “I could feel its heart beating!”  Others who reported being scared of birds upon arrival got over their fears as their peers sensitively encouraged them to touch a bird.

After they got their fill of birds, the Melton students raced over to the demonstration area, learned how to plant and cage shrubs and did not hesitate to get their hands dirty.  After all, “it’s for the birds to eat!” , they exclaimed.  Pretty soon, the students were excitedly working in teams of three and each trying to help each other plant as many shrubs as they possibly could.  It was so inspiring to watch these urban kids take to nature and the soil so fast and make the real connection between the native shrubs and the birds.

Guess ‘Hooo’ is loving our shrub habitat right now?  Owls!  Rushton is an owl magnet this year; we are up to a record 255 new Saw-whet Owls banded this season!  Although we are closed to the public for the season (we’ve had close to 1,000 visitors), we are still netting about 10 Saw-whet Owls per night, mostly young birds with a sprinkling of older adults and foreign recoveries.  We even netted a magnificent Long-eared Owl for our Bird Conservation Committee on the 13th, which was perhaps the most beautiful bird I’ve ever laid eyes on.  He was like a work of art, so regal and dignified- looking , even with his slightly cross-eyed stare.

We are thankful for our birds and thankful to Toyota and Audubon for the Together Green grant that will enable us to take action to truly show the birds our appreciation of the vibrance and character they bring to our lives, our properties and our countryside.

What will you do to give thanks for the birds this holiday season ?

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.

Well, I have lots to report from the field, so I’ll start with last week, which was an exciting one for Rushton banding station! On Monday (Columbus Day) we netted 73 songbirds of 17 species  including lots of Ruby-crowned Kinglets, our first Hermit Thrush of the season, Swamp Sparrow, Magnolia Warblers, Black-throated Blue Warblers, Common Yellowthroats, our first Hairy Woodpecker of the season, and bushels of robins and White-throated Sparrows.  All this was accomplished with 3 less nets than the usual 12, as we were slightly understaffed and strive to avoid getting more birds than we can safely process.   Woodcock, Eastern Phoebe and Cedar Waxwings were also in the area, but not netted.

We got rained out last Tuesday (10/9), but on Wednesday (10/10) we managed to band safely through the fog, mist and spitting rain, opening and closing nets as needed because we were so well staffed.  We netted 68 birds of 21 species, an exceptional day for Rushton.  Our first migrant Sharp-shinned Hawk of the fall stopped by along with two House Finch, a species we rarely see.

The rest of that Wednesday’s catch was similar to Monday with the addition of a couple of beautiful Yellow Palm Warblers, a Gray-cheeked Thrush, and a rather late Black-and-white Warbler that we first banded over two weeks ago.  She was a young female hatched this year who seemed confused about the whole migration thing; she had no fat stored aka no fuel for her imminent journey.   In fact, she actually lost a gram in those two weeks!  A recap like this gives us a glimpse into stopover ecology of these migrant songbirds.  Perhaps it’s normal for a hatching year Black-and-white to stay put for two or more  weeks before migrating or continuing migration? Or maybe she’s struggling.  After all, more than half of baby birds do not make it through their first year of life…

Another 17 species last Thursday (10/11)  included two Sharp-shinned Hawks (adult and juvenile females), our first Winter Wren, another Palm Warbler, our 26th Swainson’s Thrush and more Gray-cheeked Thrush.  Magnolia Warbler, Common Yellowthroat, and Black-throated Blue Warbler, along with Yellow Palm and Myrtle warblers continued landing in the nets.  Ruby-crowned Kinglets filled the trees and we caught our share.

This brings our day banding total for last week to 178 birds. It’s sparrow time at Rushton but still no sign of Lincoln’s Sparrow or Fox Sparrow.  Fall banding is nearing the end, but  it’s not over until the “Fox Sparrow sings!”

Yesterday, we banded our first regal White-crowned Sparrow and the first stunning Golden-crowned Kinglet of the season.  We also recaptured our little lady Black-and-white Warbler, so she’s been at Rushton for 3 weeks now!  She seems slightly healthier this week and put on a gram as if maybe she is now thinking about getting ready to migrate.

PUBlic Songbird banding continues every Tuesday and Thursday mornings at Rushton….

…when it’s not raining for the next couple of weeks until all we’re getting is sparrows and juncos.  This Thursday, we have a group of thirty 2nd graders from Abington Friends coming from 9:30-12:30pm, so you may not want to come then.  Otherwise, no reservation is needed for songbird banding, unless you’re bringing a large group.  Hours are 6:30am-11am.

The PA Young Birder event, “Owls and Their Night World” is FULL for this Friday October 19th at Rushton Woods Preserve and Farm.   Stay tuned for cancellation due to rain; the rain date will be Friday October 26, same time and place. If the event is cancelled for this Friday, we will start from scratch accepting RSVPs for the rain date.

  Please understand that this event was capped at 30 children on a first-come first-serve basis, in order for us to ensure that our small staff can safely manage the crowd in the dark while operating saw-whet owl nets and keeping the wild birds safe with minimal stress.   This limit also ensures that the children get the most our of their experience.
Of course, if you did not make it into this event you are still welcome to observe owl banding on any of the other nights we are open!  Please see below for more info.  Additionally, there will be another Young Birder Owl Night for Teens on November 9.  We are not accepting reservations for Nov 9 at this time, but will let you know when we do.
Please remember that these events are free, but donations are greatly appreciated as we are a nonprofit, and it takes a substantial amount of money and effort to keep our banding station running between equipment costs, staff time, education materials, programs etc….  If you’d like to donate, please bring cash or check and look for the donation box with the handsome, hand-carved Saw-whet owl on it!  If you’d like to be recognized for your donations, mail checks for the Bird Conservation Program to the Willistown Conservation Trust (www.wctrust.org).

Northern Saw-whet Owl Banding Program at Rushton
 Starting officially this fall on October 25, the public is invited to the Rushton Woods Banding Station for a rendez vous under the stars to observe first-hand the techniques and uses of bird banding and to learn about the biology of Northern Saw-whet Owls, arguably the cutest owls in the world. We will open from October 25 until November 21 with Thursday, Friday and Saturday evenings available, but we can accept visitors on a RESERVATION BASIS ONLY. Many people wish to visit our station with the hope of seeing these enchanting owls up-close, but our space is extremely limited.

 The monitoring of Northern Saw-whet Owls (NSWO) is a nocturnal activity whereby this small owl species is caught using a system of loudspeakers (playing their calls) surrounded by mist nets in which the owls become entangled. The data collected from this process gives scientists information about the cyclical nature of the migratory cycles of these species and their reproductive success.

This year is a shaping up to be banner year so far with banders north and south of us reporting the earliest-on-record peak of Saw-whet migration.  Normally, the peak occurs around Halloween, but many stations reported record numbers last week.  This season, the tireless Rushton banding crew has already banded 41 new Saw-whets and recaptured 1 foreign Saw-whet in just 6 nights from 10/10-10/16  (plus 3 new Eastern Screech Owls).   The floodgates (and our hands) really burst open last night with 17 feisty young  owls in our nets and many more devils left in the woods (and 34 bloody holes in our hands from 17 pairs of needle-sharp talons!).  This blows the Chester County one-night record we set last year out of the water, which was 12.  Our current total of 42 NSWO in 6 nights is more than the total number caught in 2011 after 23 nights of effort (a mere 34 owls)!  If we stay on fire like this we will far exceed our best year, which was 2010 (91 owls).

This morning we discovered that the  foreign recapture we got last night, a hatching year female (born this year), was originally banded in Ellenville, NY on 10/08/2012.  Our calculations show that this young owl flew about 125 miles in about a week’s time to arrive at the Rushton “late-night Wendy’s takeout” yesterday evening.

In addition to these voracious “woodland elves” last night, we caught (alongside an outraged owl) a very dead field mouse in the net that weighed 19.1g.  After banding the owl, we offered his mouse in a “to-go  bag”, but the owl refused to take his meal with him even though he seemed quite hungry.  Perhaps he’s  germa-phobic and didn’t like us getting our grubby paws on his “burger”.  I don’t blame him.

The experts are saying this is not a cyclical “irruption year” due to the lack of mice and voles in the north but rather a bumper crop of Saw-whet babies spilling south due to a bumper crop of voles this summer in the north.  Hence, we’ve only banded hatching year owls visiting the Rushton all-you-can-eat mouse buffet so far.

“Between migration banding in the morning for songbirds and at night for owls, we are burning the bander at both ends,” says Doris McGovern, Rushton’s federally licensed bird bander.  “Oh well, it’s owl in a night’s work!” she says, still witty even though sleep deprived.

Please reserve an evening by e-mailing Lisa Kiziuk at lkr@wctrust.org as soon as possible and note that banding is weather dependent as rain or high winds will cause the station to close.  See available dates below.

The station is located in the farm shed at Rushton Woods Preserve and Farm and the GPS address to use is 1050 Delchester Road, Malvern, PA 19355. Here’s a link to a map :  http://wctrust.org/?page_id=58  (Rushton is on the corner of Goshen and Delchester Roads, with the entrance on Delchester).  Please note that parking is at a premium and you may be asked to park in the field lot.

You will want to come when there is little or no moonlight and we can’t band if it will rain. Based on my moon chart the best times will be between October 17 and 20 and between November 8 and 19.  There are a few spaces left for this Thursday October 18th.  Otherwise, choose any Thurs, Fri, or Sat starting October 25 until Thanksgiving with the exception of the following dates:

CLOSED Days Not Open to Public Include:

November 9, 10,11, 15, and 17

Hope to see you at owl banding, but please remember to RSVP to Lisa first!

Thanks,

~Blake

Fall Banding Season Off to a Bright Start!

Last week was the first official week of Rushton’s fall 2012 public banding season.  The rain prevented us from banding on Tuesday, but the rest of the week was fantastic!  Between last week and the week before (the last week of August), we have been averaging 45 birds per day of about 13 different species each day.  Our most common southbound species include Common Yellowthroat, Gray Catbird, Ovenbird, and House Wren.  Resident species (those that do not migrate) have included Northern Cardinal, Carolina Wren, Downy Woodpecker, Song Sparrow, and Northern Flicker (some do migrate).  The American Goldfinches are all over the place feeding on the thistle, but they have not hopped into our nets yet! Instead, a few obliging female Indigo buntings picked up the slack and got in line to get their “bracelets” before their sojourn.

As for the warblers, those “butterflies of the bird world”, we have banded a stunning array so far.  Species included Black-and-white Warbler, Chestnut-sided Warbler, Northern Waterthrush (not a thrush at all), Magnolia Warbler, American Redstart, Canada Warbler, and Black-throated Blue Warbler.

Uncommon birds included a Connecticut Warbler and Mourning Warbler, both of which were young hatch year birds and looked very similar!  The Connecticut Warbler is the more elusive of the two, evading more birders’ life lists than the Mourning, partly because of its habit of foraging in low, dense undergrowth during  migration.  It breeds in open larch-spruce bogs in the north and winters in the tropics.

The Mourning Warbler is more common within its range than the Connecticut Warbler, but also tends to remain hidden in thick vegetation. The Mourning Warbler has a darker gray hood than the Connecticut and a broken rather than complete eyering.

Another uncommon, low lying, hard-to-find warbler that we caught last week was the Kentucky Warbler, and not just ANY Kentucky Warbler.  It was the SAME one we banded this summer in Rushton Woods! A young male! We have no way of knowing whether he bred successfully or at all, but we know he’s alive and preparing for his trip to Central or South America!  This is grand news.  The Kentucky Warbler is declining throughout much of its range because it needs healthy native understory as opposed to understory invaded by multiflora rose and other invasive plants, so the fact that our bird seems healthy after a summer at Rushton is good.  Hopefully a female will join him next year….

Last but not least, we banded Rushton’s very first Yellow-bellied Flycatcher on August 29th!  This is BIG NEWS!  This is a very cryptic, secretive bird that is uncommon during migration in our area.  It is a rare breeder in isolated mountain-top bogs in northcentral PA, but otherwise breeds in boreal forests and bogs of Canada.   This flycatcher winters in semi-open habitats of Central America and has been found in higher densities on shade-grown coffee plantations than sun-grown.

Switch over to shade-grown coffee , if you haven’t already, to promote habitat for birds.  Check out Birds-and-Beans or Golden Valley Farms Coffee Roasters  right in West Chester!  It even tastes better than sun-grown coffee because the coffee cherries ripen slower in the shade, thus allowing more subtle flavors to develop.

The Open House at the banding station this weekend was fun and educational for all!  There were about as many people as birds, 50 and 50.  The highlight bird species banded were of course the crowd-pleasing Carolina Chickadee and three young, molting Field Sparrows born this year!  The Field Sparrows were all in the same net together so they were obviously sticking together on their dispersal adventure.  We made sure to release them all at the same time, and they flew off together into the fields of goldenrod.  Field Sparrows are declining throughout their range due to their grassland  and field habitats disappearing.  The fact that we have them breeding here is another toast to the Willistown Conservation Trust’s land preservation efforts!

Remember that all are invited to Rushton Woods banding station every Tuesday and Thursday throughout September and October to observe songbird banding.  Nets go up at 6am and we band until 11am.  No banding if it’s raining!  We expect to start getting more Wood Thrush, Veery and other thrushes.  Then come the White-throated sparrows and juncos!

Many species of butterflies are also everywhere at Rushton nectaring from the thistle and goldenrod.  Hawk Mountain reported a 1-day record for Monarch migration on September 4th;  the hawk counters counted 883 monarchs floating past them on the ridge between 2 and 4 pm!

Our public bird banding program will run every week during fall migration beginning Tuesday, September 4!

We will band songbirds every Tuesday and Thursday through the last week of October as weather permits-we will not band if it rains.  With our nets going up at sunrise, visitors wishing to see the most birds should arrive as early as possible.  Action is often constant until 11:00am, after which the nets are closed.  Feel free to stop by for an hour before work or stay the whole morning from 6am till 11am!

Rushton Woods Banding Station is located at the Rushton Woods Preserve and Farm in Newtown Square, PA. (NOTE: GPS address is across the street from 950 Delchester Road, Newtown Square, PA).  Rushton is located at the corner of Goshen and Delchester Roads, with the entrance on Delchester Rd.  Park in the entrance parking lot and walk to the hedgerow opposite from Delchester Rd.  Hang a right when you get down to the hedgerow and quietly walk along the hedgerow past the net lanes until you see a mowed trail veering up through the hedgerow to your left.  Follow that and you’ll soon see the banding shelter.  Please approach quietly so as not to scare the birds.

Children observe a mist net in which the birds are gently caught.

Observers of all ages will get a chance to learn about birds from skilled bird banders and see all aspects of this exciting scientific process.  Birds we will be gently catching and banding are migrating south for the winter and are using Rushton as a stopover site to refuel and rest.  By inspecting the feathers of their wings, we can glean much important information about the amazing lives and the health of these beautiful birds.  The data we collect contribute to global bird conservation and helps us document the effects of our land preservation efforts on bird populations.

Bird Banding Station Open House for Families – Saturday September 8th at Rushton Woods Preserve and Farm

In addition to the normal Tuesday and Thursday public hours, the banding station will be open to everyone, Young Birders, teens and adults, on Saturday September 8  anytime from sunrise (around 6am) until we close the nets at 11am.  We are not normally open on weekends, so don’t miss this opportunity to stop by and observe our fabulous fall migrants!

PA Young Birders invited to visit Banding Station from 9-11am on Sept. 8 

During this time, other visitors and families are certainly welcome to observe bird banding, but we will kindly ask them to allow the children to take the “first row seats”.  PA Young Birders are welcome to come earlier than 9am too if they wish to see more spectacular birds.  Otherwise, from 9-11am Young Birders will be observing bird banding and learning about these amazing birds up close.  We’ll do some birding and explore the hedgerows to try to figure out what it is that’s drawing these traveling birds to this place.  We might get a chance to see other migrants too, like Monarch butterflies! Please RSVP to Blake Goll (bhg@wctrust.org or 610-353-2562 ext.20).

Lost and Found Caterpillar

Our PA Young Birder meeting last week about Monarchs and other butterflies was lots of fun!  John Black, a Master Naturalist for Edwin B. Forsythe National Wildlife Refuge in New Jersey, taught us all about the fascinating life cycles of Monarchs and what we can do for them, like plant milkweed host plants and nectar sources in our backyards.  Did you know that right before a  Monarch caterpillar becomes a chrysalis, it vomits out its insides? After all, it won’t need tough leaf-digesting organs as a nectar-drinking adult butterfly!

John even brought a butterfly-rearing tent containing live Monarch butterflies, which the children got to release, various instars of Monarch caterpillars, Spicebush Swallowtail caterpillars munching on spicebush, and Eastern Black Swallowtail caterpillars munching on parsley.  The Spicebush Swallowtail caterpillar was a favorite with its adorable “face” looking up at us!  Those eyespots are not eyes at all nor is that even its true head (it is underneath that “mask”), but this is an effective way to confuse predators.

However, we (the predators) confused the spicebush caterpillar when we accidentally shook the branch he was on!  To our dismay, the helpless caterpillar fell to the ground and landed somewhere amongst the grass where thirty minutes of rescue searching were to no avail.  John, having seen this happen many times before during his programs, knew just what to do.  He stuck a little spicebush twig with leaves into the ground near where the tiny caterpillar fell and simply went on with his program, not worried at all.

At the end of the night during cleanup, John collected his spicebush twig and the found caterpillar!  In just under half an hour, the little caterpillar smelled his life- giving host plant, found his way up to a leaf, and spun himself into his silk blanket with the tip of the leaf folded over him for the night.  Snug as a bug in a rug!  It just goes to show how sensitive these caterpillars are to their host plants.

That’s just one of the many reasons why it is so important to use native plants in your yard rather than fancy ornamentals.  It’s the native plants with which our native insects have evolved, so it’s the native plants we must plant to promote a healthy native habitat that supports native beauties like Monarchs.  If you have Butterfly Milkweed, Swamp Milkweed or Common Milkweed in your yard you may be hosting wonderful Monarch caterpillars who must feed solely on milkweed (this is what makes them toxic to birds as adults).  Other lovely native plants, like goldenrod and ironweed, will provide great nectar sources for adult Monarch butterflies.

End of Summer Observations

I can’t wait for those warblers but am having fun in the meantime just watching my bird feeders.  There are so many young birds born this summer visiting my feeders now, and even though they are starting to look exactly like the adults I can tell they are babies, mostly by their silly behavior.  I saw a young hummer at the sugar feeder the other day who had the most trouble trying to figure out where to stick his bill!  Goldfinch babies are begging from their parents incessantly at the sunflower feeder, young Tufted titmice are curiously hopping around on the floor of the deck instead of on the actual feeders, and Red-bellied Woodpeckers with gray heads are waiting patiently on the nearby tree for their mother to bring them a suet morsal or two.

Many of the adults are looking rather shaggy as they molt out of their tired “nesting season” feathers in preparation for the harsh cold weather ahead.  The goldfinches will soon lend their brilliant yellow color to the leaves of autumn as  little yellow warblers take center stage for a fleeting fall moment…
