First Short-tailed Albatross Chick Born Outside Japan Survives Tsunami and Fledges

A short-tailed albatross chick survived being washed out of its nest on Hawaii鈥檚 Midway Atoll by the that followed the in March, and fledged on June 13. That alone makes for an incredible survival story, but there鈥檚 more: This marks the first time the globally vulnerable species has bred outside of Japan.
鈥淎lthough fledging is never a guarantee, this chick is a survivor,鈥 said Deputy Refuge Manager . 鈥淗atched in the middle of a raging storm in January, it was swept 30 meters from its nest during a second storm in February, then survived the March tsunami that caused tens of millions of dollars in damage and the .鈥

The chick鈥檚 parents were banded as fledglings on Japan鈥檚 Torishima Island, the species鈥 main breeding grounds. The pair nested in the middle of a Midway Atoll decoy plot that biologists created in 2000 in an effort to lure the birds to breed there. Biologists placed dozens of decoys in the area, including models of adults and immature shorties, and played recorded birdcalls. 约炮视频鈥檚 director of seabird restoration Steve Kress, whose pioneering techniques include the use of , wasn鈥檛 surprised that it took more than a decade for the new site to take.

鈥淪ocial attraction for long-lived, highly philopatric species such as albatross needs to run for many years until birds are induced to pioneer new sites,鈥 Kress told . 鈥淥f course the role of the decoys is difficult to assess, but these and the sound recordings likely played a key role in this first nesting. I followed this project closely and I am thrilled at the outcome.鈥
The bird will spend the next two to seven years at sea before returning to land to find a mate. Most return to the place they hatched.
鈥淭he first nesting of a Short-tailed Albatross at Midway Island provides a new outpost for this much beleaguered seabird- demonstrating that the species is adaptable to this new part of its world range,鈥 said Kress. 鈥淚t also demonstrates how people can effectively encourage new colonies that reduce risk to the species by creating multiple nesting sites.鈥

From the story 鈥溾:
| Far removed from Tokyo鈥檚 hustle and bustle, I find myself in the sort of situation one rarely associates with Japan: dangling by a rope with my face pressed against cool granite, my nose filled with hot sulfur fumes from an active volcano looming above. The second-to-last thing I expect in this vegetation-free moonscape is to hear a cow. The very last thing I expect is to hear an entire herd of them. Below me white beasts lumber about a steep hillside, mooing, delivering food to their young, and then flying out to sea for more. It鈥檚 decidedly un-cowlike behavior but typical for the largest and most endangered seabird in the Northern Hemisphere, the short-tailed albatross, or what we scientists call shorties. Birds that, as you have probably guessed, sometimes sound like a bunch of cows. Loose volcanic ash fills my shoes as we skate down a scree field and through a notch in the 300-foot-high walls that stand between the steaming volcano鈥檚 vent and the world鈥檚 largest colony of short-tailed albatross. Torishima (tori means "bird," shima means "island"), a dark, jagged hulk of volcanic rock belonging to Japan, is a product of Mount Iwoyama's outpouring. The island rises from the Pacific Ocean, 360 miles southeast of Tokyo. About 160 years ago its upper slopes were frosted white with breeding short-tailed albatross. Some say a million; others, five million. Either way there were enough to make this subtropical volcanic peak look like it was dusted with snow. But while shorties may look like snowflakes from a distance, up close what you notice first is two handfuls of bubblegum-pink bird beak. The adults鈥 heads are awash with gold. Their white wings with bold black epaulettes suggest a display of military rank when they take wing. |
