New Nesting Site for Rare Albatross

A nest with a single egg is the cause of great excitement for conservation of a distinctive bird of the northern Pacific Ocean.

A nest on Midway Atoll currently being incubated by a female Short-tailed Albatross is significant as it is the first nesting for the species "outside of Japan in modern history," according to the U.S. Fish and Wildlife Service which manages the site, which is part of the Midway Atoll NWR.

"This is an amazing event," said John Klavitter, acting Refuge Manager of Midway Atoll National Wildlife Refuge, about 1200 miles northwest of Honolulu, Hawaii.

Refuge staff have been closely watching the occurrence of this rare species, which had previously been known to breed only on a couple of islands near Japan during the past few decades.

A male of this species has been observed on the island since 1999, Klavitter said. In 2000, 42 male decoys were spread in suitable places on the island, and bird calls were played to attract this particular species. The male was male bird was attracted to the decoys, preening and trying to illicit a suitable breeding response, Klavitter said.

In 2007-2008, a female albatross joined a male bird. In 2009, the pair had a closer bond, and spent more time together, according to the notes conveyed by an online posting.

Breeding has occurred in 2010, when a pair had a nest with a single egg, which is typical for this long-lived species. The male incubated a freshly laid egg on November 16, and incubation has continued, Klavitter said. The female is now atop the active nest.

The current nest is only a short distance from two of the artificial birds, as shown by photographs of the nesting site.

"It is so exciting to have these birds nest," said Klavitter, who has personally painted albatross decoys and monitored the sound system. "This is a once-in-a-career occurrence, and so incredible to have a 'dream' realized."

News of the occurrence was first posted on a popular online venue, and was one of the first stories issued by the refuge on an online venue, with the story on one popular online site, and pictures on another.

The information was presented to "build conservation awareness of seabirds in the Pacific," Klavitter said.

The Short-tailed Albatross was formerly a common species in the northern Pacific Ocean basin, based upon historic accounts including records from coastal Alaska, its numbers have dramatically dwindled to where there is just a small, remnant population, known to nest on two islands near Japan.

An increase in its distribution is significant, as it indicates a potential for a greater range of breeding success.

On Midway Island, refuge staff closely monitor the occurrence of this species locally as well as elsewhere with the middle Pacific region

Colleagues have noted two Short-tailed Albatrosses on Kure Atoll, approximately 60 miles northwest of Midway, Klavitter said. To the south, a short-tailed albatross has been visiting Laysan Island.

Kure and Midway atolls are part of the Papahānaumokuākea Marine National Monument.

With an apparent increase in the numbers of the Short-tailed Albatross, they now occur more often at places within their historic range of distribution.

These birds are "beautiful and magnificent with a wonderful plumage," Klavitter said.

The nesting of a pair on Midway Island is a "symbol of hope for conservation of seabirds," Klavitter said.

Polar Voyages Denote Birdlife of the Northern Alaska Seas

When the U.S. Coast Guard Cutter Healy departed from on the 2010 International Continental Shelf Survey, bird watcher Bill Schmoker was onboard and keeping a close eye on any birds, ready to note which species were observed during the voyage across the Arctic sea.

A teacher from Centennial Middle School in Boulder, Colorado, Schmoker has an extensive background in watching birds, which was helpful in knowing how to recognize and identify birds during the PolarTREC survey. He has monitored breeding bird transects for the Rocky Mountain Bird Observatory, been an instructor for the American Birding Association's Youth Birding Program, and photographed more than 600 species in North America.

Bird-watching at sea for weeks, was, however, a completely new experience. The voyage traveled over 5000 nautical miles.

"I was thrilled and excited with the prospect of seeing birds in the Bering, Chukchi, and Beaufort Seas and pleasantly surprised at finding bird life well into the pack ice in the Canada Basin," Schmoker said.

The first bird list - of the 26 eventually submitted to ebird, the online record repository - was for July 31st from Dutch Harbor, on Unalaska Island, a prominent place on the Aleutian Islands. The final list from the voyage was for September 6, at Barrow, Alaska, based upon observations at the end of Ogrook Street.

During the survey, Schmoker reported his observations in an online weblog, presented daily as uploaded from the ship. Topics in the more than 50 reports covered a wide variety of topics related to the scientific efforts of the ship crew, and the events and life at sea.

Schmoker's details of the birds observed, and times aboard the ship, convey a unique perspective of avifauna which had not been previously reported for the PolarTREC voyage.

Birds of the Northern Seas

During the nearly forty day voyage, 58 different species were noted according to the ebird survey reports submitted. There were various waterfowl, seabirds, shorebirds, and a lesser number of land birds. The following is a list of the species noted, with the value given a sum of the species noted for the designated localities.

The Black-legged Kittiwake and Glaucous Gull were two of the species noted more often. A highlight in latter August was seeing an Ivory Gull in the Canada Basin, which was the first time this species had been observed by Schmoker. "It was over 500 miles from the nearest land."

"In addition to the amazing birds I'd consider the 8 Polar Bears I saw to be an incredible bonus. Minke and Humpback Whales along with Ringed and Hooded Seals added to the mammal list, as did Sea Otters in Dutch Harbor."

Although bird surveys were not done each and every day - as there were other items of interest during the voyage, a summary of birds noted on the particular days when surveys were done, is available from the 26 ebird reports submitted.

More species, and a greater number of birds were reported from the surveys done at land-based sites. While sailing along, Schmoker often reported survey results with only a few species, but which noted birds of particular interest or significance.

During the voyage, Schmoker observed 14 species he had not seen before, according to the final edition of his weblog. The final addition was a small flock of Spectacled Eiders seen at Barrow, while waiting to catch a plane for his return to Colorado.

"The International Continental Shelf Survey is a multi-year project undertaken by the U.S. and Canada to retrieve seafloor and sub-seafloor data in anticipation of future extended continental shelf exclusive economic zone claims under the United Nations Law of the Sea," Schmoker said. "Bird surveys rarely are undertaken in the remote Arctic Ocean region north of both countries and so data provided to eBird from this cruise will add significant coverage to their global database of bird distribution and status."

PolarTREC 2009 Species

During the Healy 2009 cruise, foggy weather meant a lesser number of birds were observed.

Due to persistent foggy conditions, the species noted by Chris Hedge - sponsored by the NOAA Teacher at Sea program - and another observer on board, were Spectacled Eider, Pacific Loon, Northern Fulmar, Pelagic Cormorant, Red Phalarope, Black-legged Kittiwake, Ross's Gull, Glaucous Gull, Arctic Tern, Parasitic Jaeger, and Long-tailed Jaeger.

Two unusual sighting occurred on the ship. On September 5, 2009 while at the Beaufort Sea, a dead Yellow-rumped Warbler was found dead on deck. There was also a Yellow Wagtail aboard ship.

PolarTREC

PolarTREC has been underway since 2007.

"PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program in which K-12 teachers spend 2-6 weeks participating in hands-on field research experiences in the polar regions. The goal of PolarTREC is to invigorate polar science education and understanding by bringing K-12 educators and polar researchers together."

Financing for the program is provided by the National Science Foundation, and is managed by the Arctic Research Consortium of the United States, with its headquarters in Fairbanks, Alaska.
