We left behind October and its Halloween cake with the
sunrise this morning. We are now entering the dynamic month of November, where
the albatross will soon take over the island as the dominant breeding force. Lying
in my hammock yesterday evening I watched Albatross stream in like a formation
of fighter jets onto an aircraft carrier. First passing over the island to assess
the landing conditions, then circling into a headwind to glide down the runway.
Unfortunately their landing gear always seems to malfunction and I’ve seen a
few flip tail over nose when the wind is too light; they’re much more adept at
landing on the sea. Still no Laysan Albatross, bet we’re expecting them in at
any moment. The weather has been hot and still, perhaps they’re waiting for a
strong trade wind to bring them in.
Relatives of the albatross, the Wedge-tailed Shearwaters (or
wedgies for short), are getting ready to fledge their chicks. They are burrow
nesters, so to monitor their breeding Olivia has been going around with a
burrow cam (an LED illuminated camera at the terminal end of a long tube; the
image broadcasted wirelessly to a headset) to check the feathering status of
the chicks. Many chicks have reached ‘mostly feathered’ to ‘fully feathered
stage’, where they have almost completely lost their insulating down and have
developed a similar plumage to adults. Eventually the parents cue in on when
their chick is ready to fledge, and stop attending the burrow. This will prompt
the chick, when it gets hungry enough, to leave the burrow (fledge) and
experience for the first time what one can only imagine would be the thrill of
flight and the hardships of making a living at sea.
I assisted Olivia with a couple wedgie burrow plots. It’s a
repetitive task. Turn camera on, put camera in burrow, find the chick, report
its status.
“Burrow 21 fully feathered chick. Burrow 23 fully feathered
chick. Burrow 24…hmmm…this one’s difficult to see. Oh it’s a feisty
one…possibly mostly…nope fully feathered chick”.
Repeat for an hour in the hot sun.
The monotony was broken, however, by an interesting find.
“Whoa check it out, it’s a turtle hatchling!”
“Really?”
“Yeah and it’s still alive…well barely”.
Most of the lost hatchlings we find around the island have
already dried out in the sun, turtle chips. This one however had discovered the
relative shelter of a shady burrow, keeping it cool enough to stay alive and
out of the deadly heat. We took the hatchling, about the diameter of a soda
can, and carried it to the beach. Nearly stepping on a slumbering Hawaiian Monk
Seal (I didn’t notice the tracks in the sand until passing it) I made my way,
turtle in hand, to the water. Like bacon to a dog’s nose, the hatchling perhaps
hearing the light surf or smelling the salty air awoke from its heat induced
coma and began slowing flapping its flippers. Its sand encrusted eyes cracked
open, as if its biological drive to seek out the sea kicked back into gear. It
grew livelier as I set it on the cool wet sand, waving its flippers slightly
faster and attempting to move down slope of the beach. Suddenly my doubts on
its odds of survival were shaken, and once the water lapped over its body, it
was clear this hatchling stood a good chance of recovery. Within seconds of
being dragged down the beach by a surge of water, the hatchling was fully
alert. Orienting itself perpendicular to the direction of the waves, it began
vigorously paddling out to sea; lifting its tiny fingernail-sized head out of
water after every stroke. It was like
watching someone who had just been slammed by a semi get up and start running a
marathon. Amazingly resilient creatures. Vulnerable and weak, the struggle to
find the sea is only one in a series of hurtles it now faces in the open ocean.
In fact not a minute after it hit the water, a frigatebird swooped in and
attempted to pluck the hatchling from the surface. A failed attempt by the
bird, this life or death gamble will be a common occurrence for this hatchling
until it reaches adulthood. If it does manage to escape the hungry beaks of
predatory birds, the sharp teeth of oceanic sharks, and the deadly grip of
drifting marine debris, this hatchling could reach a girth of 300 pounds, and
may one day return to French Frigate Shoals to replay the drama all over again.
Resilience is key.
ReplyDeleteCan't believe you held it in your hands!
The bird sightings sound amazing. Must be strange to be surrounded by the bird you've admired for so long.
The costumes look good...very sexy.
Happy November. Hang tight.

Amazing little turtle! Great story. I still hope one day you will compile all these science-related blog entries for a book...
