Dave
Bonter came out to the island yesterday, and his presence is already
beginning to have magical effects. He went out to check nests with
Michelle today, for he's going to take over for this weekend when
Michelle's going home. They started at about 5 15, I was a slow poke
an started at 5 30. It was a decent day, and I finished north island
by breakfast.
Feeling
rather good, I returned to the RIFS lab, deposited my helmet, jacket
and tackle box, and went upstairs to grab a bowl of oatmeal where I
encountered Dave talking to Kayla and gesticulating wildly at his
phone. “Come over here!” he said as soon as he saw me.
Uh, oh,
I thought. That smile, it's simply too wide.
“Did
they hatch?! Oh my god, you're kidding!” I exclaimed. “They
hatched and you didn't even call me?!”
Nope, he
didn't. There on his nifty iPhone were pictures of two fluffy little
Black Guillemot chicks that they'd found on their way to nest-checks
in the morning, and they hadn't even bothered to inform me. Of
course. The rest of the morning was spent in scornfully throwing
dagger looks at Dave and Michelle every time they mentioned the
chicks which, believe me, was often.
However,
the cool part about the discovery, aside from the sheer awesomeness
of the chicks, was that the chicks were from another nest, not the
four-egged nest that we'd found a month ago but a neighboring nest
that we had somehow completely overlooked! The four-egged nest hasn't
hatched yet, but there's still hope, and it's good to know that there
is more than one nest on the island, raising the possibility of there
being even more than two! Time to perhaps re-embark on a guillemot
nest hunt?
It
got extremely hot after breakfast. Dave and Michelle still had to
finish their nest-checks so they donned their helmets, drank
plentiful water and headed out while I settled myself in the coolness
of the RIFS lab and read a great paper on Black Guillemot egg
fostering (Divoky and Harter 2010) where they describe a case of a
pair of guillemots taking over the nest-cavity of another pair and
kicking out the two eggs of the first pair but then, eventually, for
some odd reason, gathering the eggs back into the nest-cavity and
incubating them along with an egg of their own.
Two
interesting results: 1) the egg of the usurpers didn't even hatch
while the eggs of the previous owners did and 2) the eggs of the
previous owners hatched ~28 days after the commencement of
re-incubation. 28 days is the normal incubation period for Black
Guillemots but the eggs had been
left out in the cold for over 14 days! A case of suspension of
development in extreme weather conditions? Perhaps. It gave me hope
for the four-egged nest that has been due for a while now.
After
lunch, it was data-entry time. Dave had sat down with us the
yesterday and pointed out that there were a lot of nests where no
chicks had been seen for over seven days, nests where the chicks were
probably dead. Thus we needed to finish up the “Nest Summaries”
on all such nests, filling out all the information – GPS
references, number of eggs, number of chicks, egg measurements, cause
of nest failure, habitat etc. – for each nest. It was a tedious
task, not made any easier by the fact that we were very full and
sleepy after lunch.
To
make it more interesting, we decided to talk only in French.
Data-entry usually involves one person reading something to the
effect of “Nest 315, two chicks; Nest 8, no chicks...” from the
field notebooks and the other person typing in the data. Today
data-entry sounded more like “trois cent cinquante..
wait, no, quinze! Deux
chicks!” (we didn't think to look up the French word for chicks
beforehand) and we finally realized that it wasn't quite working when
I came to the day's entry for 12H225, the birds at which nest have
been affectionately named Grape Jelly and Toast by Michelle.
“Deux
cent... vingt-cinq! Oooh c'est Grape
Jelly et Toast!” I
exclaimed.
Michelle
turned to me with a horrified look on her face and cried, “Wait,
what?! Grape Jelly ate Toast?!!”
Needless
to say, much time was wasted in paroxysms of laughter. But we refused
to quit, powering through even the 280s and 290s, the horrid
quatre-vingt series.
Realization of the day: French numbers are especially hard because,
as Michelle put it, “you have to add and multiply in the same
sentence!”
Once
we tired of data, because it never ended so the only way to end it
was to tire of it, we headed out to have a “Nearest-neighbor Party”
with Dave. One of the things that we measure on nests is the distance
to the three nearest nests, a job that, ideally, requires three
people: a note-taker, a one-end-of-tape-measure-over-nest-holder, and
a running-around-with-other-end-of-tape-measure person. We needed to
measure the nearest-neighbors for a bunch of new nests that we'd just
started monitoring, so, taking advantage of Dave's presence, we
dragged him out into the colonies, turning it into a party.
First
stop: Black Guillemot nest. Finally, after a whole half-day of
waiting and snarkily commenting on Dave and Michelle's exuberance, I
got to reach my hand into the narrow rock fissure and pull out the
most adorable baby bird I have ever seen.
It
took me a solid minute or two to even find the tiny little thing. I
was groping around under the rock going “Uh.. Dave.. I don't think
they're here” when my fingers suddenly felt something warm, fuzzy
and downy, and I let out a squeal of joy. “Ah, I think she found
it, Michelle,” Dave remarked drily.
Me, poop-stained shirt, silly smile, adorable guillemot chick |
The
rest of nearest-neighbor party was, admittedly, not as fun
and exciting, but at least we got things done. Plus, we saw a
Red-breasted Nuthatch fly into the intertidal to, presumably, forage
for insects which was pretty interesting since they tend to normally
forage along tree branches.
As
we were walking towards Transect 5, Michelle pointed out an awkward
gangly-looking Black-backed chick that was just starting to lose its
down and molt in its flight feathers. “Doesn't it look like an old
man?” Dave asked, his tone dripping with sincerity. “... an old
man crossed with a vulture!” I think it was at about that point
that I began to feel at a loss for words.
