I haven’t brought you up to date on last week or this week yet because it has been pretty hectic for us sleep-deprived, cranky bird banders.  This is the time when we are working hard banding back to back: nights for Saw-whet Owls and mornings for the last fall songbird migrants.  This sounds crazy, I know;  why don’t we just quit the songbird banding and focus on the owls?  The reason is because it is very important to gather as much songbird data as we can up until the very end when the flight peeters out so as to flesh out the entire picture of the fall migration.  Quitting songbird banding too early could mean we miss the unexpected migrants on the periphery of the fall movement.  So we soldier on for the love of birds and the loyalty of scientific research.

We went for songbirds last Tuesday (10-25) and Wednesday (10-26) morning and were surprised by large numbers of migrants still moving through.   We banded 59 birds on Tuesday, including a feeding flock of snarly Chickadees and Tufted Titmouse.  Wednesday was the  notable fallout day, with migrant birds virtually dripping from the trees and carpeting the fields;  the hedgerows were alive!  A large flock of Cedar Waxwings eluded us all morning by staying high in the canopy, but we banded 70 birds that day, including a late Nashville Warbler, several Yellow-rumped Warblers, lots of White-throated Sparrows, a handful of lovely little pink-billed Field Sparrows,  a flock of young Hermit Thrush, and the first batch of Dark-eyed Juncos of this year!  It was good to see the Juncos again… to hear their familiar metallic chipping in the shrubs, and to watch the flash of white outer tail feathers as they jovially flit about the hedgerow….almost like welcoming old friends back for the holidays.  Of course, Juncos are the first sign of impending snow, and they indeed brought the snow with them.

Perhaps last Wednesday was so busy because all the birds knew  they had to get a move on before the rain of last Thursday and the snow of Saturday.   In the calm before the storm they can feel the pressure changing and thus sense what is to come.  In any case, Wednesday was a day to be remembered.

I went home briefly for lunch after morning banding and stepped out of my car in my driveway to a birder’s paradise.  There were birds EVERYWHERE.  I think I left the keys in the ignition with the car running and the door wide open as I grabbed my binoculars from the dashboard and excitedly scanned the yard.  A Brown Creeper was creeping 5 feet away from me in a magnolia tree, and a Ruby-crowned Kinglet was flitting around hunting insects in an ornamental tree 2 feet in front of me.  Further into the yard was a Hermit Thrush distinctively bobbing its tail up and down under the blue spruce.  Suddenly a woodpecker whizzed past the spruce and into the arborvitae next to the house.   Could it be?  It was!  A beautiful male Yellow Bellied Sapsucker, only seen in my yard during migration!  I ventured further into the shallow woods behind my house, lured by the restless flurry of birds.  There I saw about 20 Robins, the Hermit Thrush (which followed me and was spying on me as I find they often do),  an abundance of Yellow-rumped Warblers, a Golden-crowned Kinglet, lots of White-throated Sparrows, and yet another Yellow-bellied Sapsucker (a juvenile) tap tap tapping on an oak.  What a day!

Speaking of Golden-crowned Kinglets, on that same Wednesday (10-26) we had an interesting catch, if you can fairly call it a catch.  Lisa, Lou, Doris and I were about to disperse for another net run when a little Golden-Crowned Kinglet came careening into the banding lodge and flew up into the skylight.  She didn’t have enough speed to injure herself fatally because in order to hit the skylight she had to dip down and then up.  However, she did bump her head unexpectedly and then sat on the railing totally stunned.  I saw the whole transaction and am still not sure who was more stunned: me or the bird.  As Lisa and I were standing there staring at the bird in disbelief, Doris quickly reacted and said, “Grab it and band it!”    Lisa and I looked at each other in shock and then looked at the bird.  She seemed okay, so I gently picked her up and banded her.  She perked up and flew away after we processed her, but she didn’t fly far.  We saw her perched in a tree 5 feet away looking at the banding shelter and then at her ankle as if thinking, “What on earth just happened to me?  One minute I was flying and the next I was stopped by an invisible wall and then picked up by a giant who stuck this shiny thing on my ankle!”  She got over it fast and soon went back to foraging.

That day, we also got a recap White-throated Sparrow, which was exciting because the band looked like an old band.  Getting a recapture songbird from someplace else is very unusual; most all the recaps that we get are our own birds that we banded just a few days ago at Rushton  (they either haven’t moved on yet or are here to stay).  This White-throated Sparrow ended up being  our own as well.  However, looking back at the records, Doris discovered that it was first banded at Rushton as an After Hatching Year (AHY) bird in December of 2009.  This means the bird is over 3 years old and probably spends its winter in Rushton Woods Preserve every year!  Interesting example of winter site fidelity.

Yesterday (11/2) was pretty slow for songbird banding, with only 34 birds, which is probably how it will be from here on out as fall migration comes to a close.  Tuesday (11/1) yielded 58 birds including a gorgeous male Golden- crowned Kinglet, an exquisite Brown Creeper, the first handsome Fox Sparrow of the season, and a bizarre White-throated Sparrow with bright orange lores instead of the usual yellow  (referring to the area right in front of the eyes).   There are still Palm Warblers moving through the area in decent numbers as well; they were at Rushton yesterday, and I saw one at Okehocking on Sunday while walking in the snow with my pug.  Next week will most likely be the last week of songbird banding before we close for the season.  As always, you’re welcome to come out and observe Tuesday and Thursday.

As for the Northern Saw-whet Owl (NSWO) banding, the season is well underway.  We are going out every night this week to take advantage of the peak of the season and the relatively dark nights before the full moon thwarts our efforts next week.  (Moonlit nights are not good for catching NSWO because they can see the nets better and tend to move less because they know they are more visible to predators like Great Horned Owls, Screech Owls, and Barred Owls.)

I believe our total for this season so far is 23  Saw-whets. The season started out a couple of weeks ago with a very slow trickle of none, 1, or 2 owls a night until All Hallow’s Eve when we got 7 ferocious Halloween NSWOs.  They were especially feisty that night with talons flailing and beaks clapping…maybe they knew it was the Devil’s night!  Tuesday night (11/1) we got 8 Saw-whet owls including a recapture banded a few nights ago by us.  Last night, we banded 4 new Saw-whets.  This week we also banded a gorgeous red-phase Eastern Screech Owl, which brings our screech total of this season to 4 (3 red and one gray).  Screech Owls can be predators to Northern Saw-whet Owls, but so far (knock on wood) our resident Screeches have been behaving themselves.   We enjoyed hearing them singing last night amidst the meowing contact calls of the Saw-whets in the hedgerows.

All of the other Saw-whet banding stations nearby are starting to get the owls in greater numbers as well, but no one is seeing the abundance of last year.  Even Scott Weidensaul’s 3 stations near Schuylkill Haven, PA (“the Big Boys”) have only about 31 owls as of November 1, which is slightly behind their worst season in 2006, when they had 33 for the date, and well below their 10-year average of 64 for the date.   This year is definitely not an irruption year for the little fuzzballs.  Perhaps there are too many rodents up north to warrant many of the owls to migrate south or perhaps the breeding owls were not as successful this summer.

In any case, this is shaping out to be the best week this year so far for migrant Saw-whets to reach Rushton and jump into our nets.  If you would like to observe the mistnetting and banding process of these wondrous little creatures of the night, remember that you must contact Lisa Kiziuk first (lkr@wctrust.org) to make an owl appointment. Nights are getting frigid so layer up!

kyra & sawwhet BINNS IMG_1806 copy

Please note that this Friday (Nov 4th) is the PA Young Birder meeting at Rushton from 7-9pm, so owl banding will be closed to the public during that time, unless you have RSVPed your child for the event.  The night should be a wild one, with Saw-whet Owl banding and presentations, owl ‘Seek and Find’ in the farmshed, owl art with Adrian Binns,  s’mores and owl stories around the bonfire, and even short night hikes for those brave souls that really want to get a feel for the natural world at night!

There’s a lot going on in the woods,

P.S. Our bird conservation program has really taken flight this past year, and we love being able to connect the public with our birds in such an intimate way.  The Willistown Conservation Trust’s main goal remains protecting the land we love, but we have found that birds (in addition to farm fresh food) are a great way to get people to appreciate the land on a deeper level.  Furthermore, our bird banding research contributes to global bird conservation efforts while guiding local habitat management for the benefit of birds and other wildlife.  We appreciate all the help we can get as we are a non-profit organization with big dreams!  If you  have benefitted in some way from any of our programs or if we have provided you with a life-changing moment with one of our wild birds, please consider giving back.  Anything helps!

Final Fall Fallout of Migratory Songbirds & Our First Saw-whet Owl of the Season!

October 22, 2011 By Communications Team

Last Friday (10-14), we banded 56 birds to the delight of my adult class (age 50+) from Widener’s Osher Lifelong Learning Institute.  After studying birds, bird banding and bird conservation in the classroom, the enthusiastic students came out to Rushton Woods Preserve to experience the banding production in person.  They were thrilled to touch and be so close to these wild feathered beauties and were pleasantly surprised at the diversity of species:  Eastern Phoebe, 5 Palm Warblers, 3 Myrtle Warblers, 1 Common Yellowthroat, 4 Black-throated Blue Warblers, lots of sparrows, 1 Gray-cheeked Thrush, towhee, goldfinch, cardinals, Carolina Wren, and 1 late CATBIRD!

The net over the compost pile was very busy that day with over 15 birds in the net at once during the mid-morning net check.  Doris was packing 2-3 birds of the same species in each bag (we need more hand-made bird bags if you can sew and want to lend a hand!).  Poor Doris also suffered deep puncture wounds during that same net check from an ungrateful mole or vole that she rescued from the net.  “Don’t get no respect, even from rodents!”, she cried.

This past Tuesday (10-18) was our second big fallout day, probably the last one for this fall.   We banded 93 birds of 20 species, which is 7 birds over Rushton’s previous record of 86!  A Northern Parula Warbler was the best of 6 warbler species, and several Golden-crowned Kinglets were new for this year.  Our loyal volunteers Alice, Lou, and Godefroy extracted non-stop and  kept the birds safe.  Win and Justin helped at the open and went to work saying, “Here are 6 birds.  There are 2 more in #7 and 12 in #6.”   That was 7:45 and we never stopped until after 10.   Doris says, “No bird was held more than 90 minutes, which is long for Rushton, but nothing for the big banding stations which routinely hold birds for longer.”

Thursday and Friday of this week were slower, with probably more High School kids than birds.  About 100 honors students from Conestoga High School’s Environmental Science class came out to Rushton over the past two days.  They had the chance to visualize and experience concepts they have learned or will learn in the classroom this year by rotating through 3  stations: a woodland ecology walk, tour of the sustainable CSA farm, and bird banding and conservation.  The students were impressed with the common birds we all sometimes take for granted like the handsome American Robin and Northern Cardinal and the charismatic Tufted Titmouse.  The very last catch of the day was a stunning Sharp-shinned Hawk, which the kids got really excited about.  The cell phones immediately came out of pockets and were snapping pictures left and right!  This is probably the same hawk that we have occasionally seen darting in and out of the hedgerows and even dive-bombing Lisa one day as she was closing the nets.  I think the Sharpie was angry that she wasn’t leaving the net up to facilitate his lunch endeavors.

As for the Northern Saw-whet Owls (NSWO), we were off to a very slow start.   For the first couple of weeks, we ended up empty-handed every night  except for a red-phase Eastern Screech Owl two Fridays ago  at 8pm and then again at 11pm.  He just couldn’t get enough of our nets, apparently.  Let’s just hope he has learned his lesson and stays away once we really start catching saw-whets (screech owls are a predator of NSWO, believe it or not).

We don’t know what’s taking the Saw-whets so long, but it may be related to this crazy wet weather we have been having (which seems to have delayed this year’s  songbird migration as well).  There is also some speculation that this year was not a very successful breeding year for the NSWO, and therefore the number of young “Hatching Year” (HY) birds is much lower than last year.  Since most of the owls we band are HY birds, we don’t expect to band as many this year as last. (The older more dominant males tend to prefer to stick out the winter on their northern territories rather than migrating south with the young owls and the females. )

The NSWO is also an irruptive species closely tied to the pine tree seed crop up north.  Last year was an irruption year during which we had more saw-whets coming south than usual because the pine trees did not produce as many seeds as the previous year, which caused the rodent population (owl food) to plummet.  When food up north is scarce, more owls travel south for the winter.  Bird migration is related to food scarcity, not cold weather.  Most birds, even some hummingbirds like the Rufous, are well adapted to dealing with cold weather.

You can imagine our delight last night (10-21) when we finally caught our first Northern Saw-whet Owl!!!  It was a cute-as-a-button feisty young female weighing in at about 92 grams.  It was about 9:00 at night when she found her way to our nets while investigating our audio lure that incessantly plays the male’s territorial call.  Everyone was ecstatic, and even men’s voices were raised an octave or two as they ‘ooed’ and ‘aahed’ over the little owl.  As for myself, I was a little intimidated by her mesmerizing yellow eyes that seemed to be boring into my soul from some wild place and “reading my mind”, as one woman said.

Alas, there is hope for this year’s owl banding season! Remember to contact Lisa Kiziuk (lkr@wctrust.org) if you are interested in observing owl banding.  Songbird banding will also continue on Tuesday and Thursday mornings for the next couple of weeks.  No reservation required for songbirds.

And speaking of Lisa, congratulations to her on winning the DVOC (Delaware Valley Ornithological Society) Rosalie Edge Conservation Award for her tireless bird conservation work!  Without her vision, the Willistown Conservation Trust’s banding station at Rushton Woods Preserve would never have become a reality.  Today, the Rushton bird banding station is not only a reality but a wonderful destination where adults and children of all backgrounds experience some of nature’s finest works of living art while learning about the importance of such scientific research in the understanding and ultimate conservation of our nation’s feathered bounty.  Thank you, Lisa, for  making your dream come true and for all you do for the birds.  I know Rosalie Edge would be proud of you.

Final Fall Fallout of Migratory Songbirds & Our First Saw-whet Owl of the Season!

October 22, 2011 By wctbirds

Last Friday (10-14), we banded 56 birds to the delight of my adult class (age 50+) from Widener’s Osher Lifelong Learning Institute.  After studying birds, bird banding and bird conservation in the classroom, the enthusiastic students came out to Rushton Woods Preserve to experience the banding production in person.  They were thrilled to touch and be so close to these wild feathered beauties and were pleasantly surprised at the diversity of species:  Eastern Phoebe, 5 Palm Warblers, 3 Myrtle Warblers, 1 Common Yellowthroat, 4 Black-throated Blue Warblers, lots of sparrows, 1 Gray-cheeked Thrush, towhee, goldfinch, cardinals, Carolina Wren, and 1 late CATBIRD!

The net over the compost pile was very busy that day with over 15 birds in the net at once during the mid-morning net check.  Doris was packing 2-3 birds of the same species in each bag (we need more hand-made bird bags if you can sew and want to lend a hand!).  Poor Doris also suffered deep puncture wounds during that same net check from an ungrateful mole or vole that she rescued from the net.  “Don’t get no respect, even from rodents!”, she cried.

This past Tuesday (10-18) was our second big fallout day, probably the last one for this fall.   We banded 93 birds of 20 species, which is 7 birds over Rushton’s previous record of 86!  A Northern Parula Warbler was the best of 6 warbler species, and several Golden-crowned Kinglets were new for this year.  Our loyal volunteers Alice, Lou, and Godefroy extracted non-stop and  kept the birds safe.  Win and Justin helped at the open and went to work saying, “Here are 6 birds.  There are 2 more in #7 and 12 in #6.”   That was 7:45 and we never stopped until after 10.   Doris says, “No bird was held more than 90 minutes, which is long for Rushton, but nothing for the big banding stations which routinely hold birds for longer.”

Thursday and Friday of this week were slower, with probably more High School kids than birds.  About 100 honors students from Conestoga High School’s Environmental Science class came out to Rushton over the past two days.  They had the chance to visualize and experience concepts they have learned or will learn in the classroom this year by rotating through 3  stations: a woodland ecology walk, tour of the sustainable CSA farm, and bird banding and conservation.  The students were impressed with the common birds we all sometimes take for granted like the handsome American Robin and Northern Cardinal and the charismatic Tufted Titmouse.  The very last catch of the day was a stunning Sharp-shinned Hawk, which the kids got really excited about.  The cell phones immediately came out of pockets and were snapping pictures left and right!  This is probably the same hawk that we have occasionally seen darting in and out of the hedgerows and even dive-bombing Lisa one day as she was closing the nets.  I think the Sharpie was angry that she wasn’t leaving the net up to facilitate his lunch endeavors.

As for the Northern Saw-whet Owls (NSWO), we were off to a very slow start.   For the first couple of weeks, we ended up empty-handed every night  except for a red-phase Eastern Screech Owl two Fridays ago  at 8pm and then again at 11pm.  He just couldn’t get enough of our nets, apparently.  Let’s just hope he has learned his lesson and stays away once we really start catching saw-whets (screech owls are a predator of NSWO, believe it or not).

We don’t know what’s taking the Saw-whets so long, but it may be related to this crazy wet weather we have been having (which seems to have delayed this year’s  songbird migration as well).  There is also some speculation that this year was not a very successful breeding year for the NSWO, and therefore the number of young “Hatching Year” (HY) birds is much lower than last year.  Since most of the owls we band are HY birds, we don’t expect to band as many this year as last. (The older more dominant males tend to prefer to stick out the winter on their northern territories rather than migrating south with the young owls and the females. )

The NSWO is also an irruptive species closely tied to the pine tree seed crop up north.  Last year was an irruption year during which we had more saw-whets coming south than usual because the pine trees did not produce as many seeds as the previous year, which caused the rodent population (owl food) to plummet.  When food up north is scarce, more owls travel south for the winter.  Bird migration is related to food scarcity, not cold weather.  Most birds, even some hummingbirds like the Rufous, are well adapted to dealing with cold weather.

You can imagine our delight last night (10-21) when we finally caught our first Northern Saw-whet Owl!!!  It was a cute-as-a-button feisty young female weighing in at about 92 grams.  It was about 9:00 at night when she found her way to our nets while investigating our audio lure that incessantly plays the male’s territorial call.  Everyone was ecstatic, and even men’s voices were raised an octave or two as they ‘ooed’ and ‘aahed’ over the little owl.  As for myself, I was a little intimidated by her mesmerizing yellow eyes that seemed to be boring into my soul from some wild place and “reading my mind”, as one woman said.

Fall Warblers are Back in Town

September 1, 2011 By Communications Team

…. “Those little nimble musicians of the air, that warble forth their curious ditties, with which nature hath furnished them to the shame of art.”
~Izaak Walton

Female Prairie Warbler

The little colorful warblers have indeed begun streaming down from the North to grace us with their fleeting presence this autumn.  I think the hurricane may even have helped to stir them up a little. On the day of Irene’s visit, before it got really nasty, I spotted a visiting Black-and-white Warbler and a lovely pair of American Redstarts hunting insects in my yard, and Doris (our Master Bander) had a Canada Warbler in hers.  Unfortunately, we won’t hear the warblers’ “curious ditties” much, if at all, because they are more cryptic during fall migration in both voice and plumage.  This is why you hear the term “confusing fall warblers”; identification is extra challenging because they are not in their bright breeding plumage, differences between species are more subtle, young males born this year look an awful lot like adult females, and song is no longer a dead giveaway!  But if you want to start studying your bird songs in preparation for next spring, here is a great resource: Nature Instruct.org.

And of course, you are invited to drop by our banding station (no sign-up required) this fall to see, touch, and learn more about these beautiful migrants that visit Rushton Woods Preserve.  We are in the process of clearing vegetation from the net lanes and finishing data entry from summer MAPS banding.  We are eager to start the passerine banding season next week on Tuesday September 6 and will band every Tuesday and Thursday from sunrise to 11am (when it’s not raining) through Nov 1st.  Public Northern Saw-whet Owl banding (by reservation only) will begin the week of October, probably Friday October 7th.  More on that to come…

Check out these unbelievable pictures of an incredible early morning fallout of migrants, mostly warblers, this past spring on Machias Seal Island, Canada.   Be sure to scroll through all 12 pictures!  Those poor birds are so exhausted they are letting the photographer pick them up in his hand.  We forget how amazing a feat these migrations are for such small creatures… It literally almost kills them.  I wonder what these birds are saying to each other…Anyway, this is the type of fallout we are hoping for at Rushton this fall! Miracles happen, right?

Speaking of fallouts, did you hear about the exotic seabirds that Hurricane Irene blew in last week?  Birders were going crazy along the Delaware River and Cape May checking off life birds they would normally have only been able to see by taking a trip out to the sea or the islands.  These seabirds travel effortlessly in the relatively calm eye of the storm and then drop out into ‘new worlds’ when the storm begins to weaken.  Sightings included 10 species of terns including a Bridled Tern and a Sandwich Tern (Who thinks of these names?), a Jaeger, and even a Whitetailed Tropic Bird, normally seen in Bermuda and the Caribbean.  Very exciting.

Sanderling
Some South-bound Sanderlings and Ruddy Turnstones were also "beached" during Hurricane Irene. This is a Sanderling being banded this past spring for the Delaware Shorebird Project.

Although some birds can travel unscathed through the eye of a hurricane, I’m sure Irene forced the burgeoning Monarch butterfly migration to a screeching halt!  All the rain in general last month seems to have slowed the butterflies down; we didn’t find many Monarchs or other butterflies during last week’s PA Young Birder meeting, “Monarch Madness.”  We did find and observe one tiny Monarch larvae, one Spicebush swallowtail adult, and some praying mantises! The children had fun bug hunting and learning all about Monarch life cycles and migration while wearing their “thinking antennae!”  Please read more about this community event and see the great pictures by photographer Amanda Mahnke in The Malvern Patch!

This month’s PA Young Birder meeting will take place at Rushton Woods Preserve on Saturday September 24, 9-11 AM.  The little birders will discover the fabulous fall migrants as they join us for songbird banding.  They’ll see that around this time of year, Rushton becomes a hoppin’ Bed and Breakfast Inn for a multitude of different bird species, many of which we don’t see during any other time of the year.  Each Jr. Birder will also get to spend a life changing personal moment with some of these special avian visitors before they continue on their way south for migration vacation!  Interested Jr. Birders should RSVP to Lisa Kiziuk (lkr@wctrust.org).

Side note:  Don’t forget to contact me (bhg@wctrust.org) if you are interested in volunteering to monitor our milkweed patch at Rushton for monarch larvae or to tag migrant adult monarchs this month.  The data from these citizen science projects is crucial to Monarch butterfly conservation.

There is yet another interesting migration event that I should let you in on….  Nighthawks. Most active during dawn and dusk, they say these strange birds are the missing evolutionary link between diurnal birds and owls.  They sort of look like owls with their cryptic coloration, they fly like bats skillfully catching mosquitoes out of the air, and they have the word ‘hawk” in their name.  So what is it?  It is actually a member of the Nightjar family and related to the Whipoorwill.  Right now, these strange little birds are migrating by the hundreds to South America, and you can view this fascinating phenomenon at the Haverford College Observatory from 6-8pm any evening from now until September 11.  Observers saw 648 migrating nighthawks last night!   Better than a fireworks show! Read more in the BCDC blog 

Unfortunately, migration may be the only time most people see nighthawks in this area.  Although their “peent” call used to be a familiar sound in cities and towns, they are now thought to be declining through most of their range as a result of changes in roofing.  They prefer to nest on old fashioned, flat peastone gravel roofs and hunt for insects attracted to city lights.  Project Nighthawk is an Audubon initiative encouraging people to create gravel nest patches on their roofs.  This is a project we hope to become involved with in the near future as well! Go to the Project Nighthawk website for more info.

And last but not least, while we are sort of on the topic of hawks…here are two remarkable videos about hawks that are worth watching:

“Parahawking” over the skies in Nepal (watch in HD)

Goshawk in slo-mo (only works in full-screen mode)

Oh and don’t forget to plan a visit to Hawk Mountain this Fall!  No Goshawks so far, but they’ve had 700 raptor migrants of 14 species in addition to many species of warblers.  Click here to see the count.  And since we like Monarchs too, I’ll tell you that their Monarch Celebration day is September 17th.

Have fun, and I hope to see you at the Rushton banding station soon!
