Since
its conception on Sunday, 15 July, Gull Chick Banding Crew 2012 has
been, quite literally, rocking it. For us – that is, Dave, Julie
Ellis, Justin Stilwell, Galina, Michelle, Luke DeFisher, Caleb
Arellano, Michelle Lapointe, Steven and Bill – the day starts at
daybreak.
We
meet at the Commons at 5 15 to grab some pre-breakfast, usually in
the form of cereal or a banana, and then head down to the Grass Lab
to pick up chick banding gear and for a whole day of sprinting across
rocks after Herring and Great Black-backed chicks.
For
each chick we take a blood sample, put on two bands – a metal USGS
band and a plastic Field Readable band, each with a unique code –
and measure the bird's weight, tarsus and head + bill. The blood
sample helps us determine the sex of the chick, in addition to other
DNA analysis; the bands help us identify the bird as an individual
every time we spot it, helping us track its movements as it migrates
south for the winter and then, potentially, returns to the island to
breed; and the measurements help us answer a range of questions, from
how hatch order affects growth to do older birds have healthier
chicks to difference in size by sex.

Simple
as that may sound, the process of collecting this information
requires the chick to be stuffed into a modified-pant-leg bag and
pinned down on its back by one person as the other person works on
its legs, trying to avoid the poop that tends to spurt out of its
rear end and keep the needle, band and calipers steady as it delivers
powerful kicks with its webbed and sharp-toed feet. I wouldn't trade
the experience for the world.

And
the crew just gets better everyday. The very first day we broke the
all-time record by banding 77 chicks. The next day we decided to push
it and got to 85. The next day, yesterday, we just didn't stop and
went up to 113. Today, we got about a decent 60/70 but worked from
sunrise to sunset, with Justin finishing up the measurements on the
last Black-backed just as the sun dipped over the horizon.
I
must say, it is pretty darn awesome to put shiny, new, “adult”
bands on chicks that I've kept track of since day one, picking up the
little squealing fuzzballs, dabbing their bellies with marker and
stuffing them in a tiny bag to get a reading like 60 grams on the
scale. Those chicks now weigh between 800 to 1500 grams, have lost
all their down and are already running around, flapping their wings,
a few even succeeding to get about a foot off the ground.
The
most bittersweet moment today was banding Laighton “A” chick. It
was my first chick to hatch. I remember when, two months ago, Brendan
and I snatched it and his sibling from their nest and Dave taught us
how to poke needles in their legs to take a blood sample. I was so
flustered, I think I ended up getting about half a drop. Today I saw
it near his nest as we were heading up to P-K to band some chicks.
“Wait,
Justin!” I called out., pointing to the chick “Can we band him?”
“Sure,
go for it!” he replied
“OK!”
I said and booked it into the bushes. But A chick was too quick for
me and ran down the trail, flapping its wings as I gave chase. It
reached the end of the trail and turned right, heading upslope, and,
suddenly, with a strong flap, it was in the air!
“He
is FLYING!” I cried, doubling my speed.
“Hang
on!” I heard Luke call out of nowhere.
He
had guessed I'd be chasing the chick up that trail, so he sprinted
out from around the corner, throwing his bag at the bird to startle
it back to the ground. It worked! Caught off-guard, the chick fell
back to the ground and Luke was on it in the blink of an eyelid.
Needless
to say, I got a whole capillary-tube full of blood from Laighton “A”
chick this time, around and only had to poke it once.
There
are many more chick grabbing and banding stories from the past few
days, if only I had the time and energy to type them out right now.
However, things are definitely coming a full circle as we approach
the end of chick banding week. The banding crew consists of four out
of the ten of us that took Field Ornithology at the beginning of my
Appledore sojourn, the chicks that started out as eggs are beginning
to look and behave more and more like their parents – though
they'll retain their brownish juvenile plumage for four more years –
I'm beginning to think about Ithaca and everyday showers and people I
haven't seen in over two months and... and... civilization
again. Scary thoughts that creep up on me as I am sitting on the deck
watching a sunset or write make a note of when I need to measure a
chick again, only to realize that I won't be here anymore on that
day. I can't imagine life without constant yeow calls,
nest-check stories, dessert anticipation at dessert, Shoe Tree
evenings and all of the amazing, cool, awesome people
that I've met or re-met here.
But
I'll save that for the next post.
Here's
to a continuation of the awesome chick banding run for the rest of
the week! As Luke put it, “Eat. Sleep. Gull. That's it.”
I have so enjoyed reading your blog and keeping up with your gull adventures on Appledore! I've only made it out a few times this summer, mostly to help with Celia's garden, but I'm due to return shortly. Should I run into you, I'll make sure to say hello. I sense you will not be on island much longer and as you know, you will surely miss it. But, you most likely will return to enjoy those special sunrises and sunsets - not to mention all the gull chasing. You've had quite a summer! Best of luck.
ReplyDeleteThank you, I'm glad you enjoyed my blog! Unfortunately I'm leaving on Monday morning, but I'm sure the call of the gulls will entice me back here next summer...
