The Hatchling



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.

  1. Resilience is key.

    Can'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.

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