Black-footed Albatross – birdfinding.info

Birdfinding.info ⇒ The common albatross of the eastern North Pacific, often seen in numbers on pelagic trips out of ports spanning from Alaska to Baja California—at any time of year, but most numerous from March to October. Generally most numerous off of southern California in March and April, then shifts northward, with greater numbers present off of Alaska, British Columbia, Washington, and Oregon from August to October. It can also be found in Japanese waters east of Honshu and Hokkaido, and south to the Ogasawara Islands. In Hawaii large numbers breed in parts of the Northwest Chain. A few are sometimes seen among the main islands: on pelagic trips, especially in Kaulakahi Channel, and as visitors to the Laysan Albatross colonies on Oahu at Ka’ena Point and on Kauai at Kilauea Point.

Black-footed Albatross

Phoebastria nigripes

Family: Diomedeidae

Breeds in Hawaii and offshore islands of Japan. Disperses throughout the North Pacific and adjacent seas.

Breeding. Nests in November or December, mostly in large colonies on remote atolls but also in scattered pairs and small groups on headlands of larger islands. Most juveniles fledge in May and June.

In Hawaii, it breeds only in the Northwest Chain, where the largest colonies are on Midway Atoll (approximately 28,000 pairs) and Laysan (~23,000). Other colonies are on Pearl and Hermes Reefs (~6,100), French Frigate Shoals (~5,000), Kure (~3,500), Lisianski (~2,100 pairs), Necker (~100), Lehua (~40), Nihoa (~30), and Ka’ula (~5).

Also breeds in the western North Pacific on Wake Island and Japan’s offshore island groups. The Japanese population numbers several thousand, with the majority (~2,500 pairs) breeding on Torishima and a few hundred on Mukojima. There are smaller colonies, a few pairs each, on Hachijyo-kojima and Aogashima in the Izu Islands, Chichijima and Hahajima in the Ogasawara Islands, and on Kita-kojima, Minami-kojima and Koubisho in the Senkaku Islands.

Since around 2000 a few pairs have bred on Mexico’s Isla San Benedicto, and possibly also on Guadalupe.

A few Black-footed have been found visiting the expanding Laysan Albatross colonies on Kauai and Oahu, and might be expected to nest there eventually, as they breed in mixed colonies in the Northwest Chain.

Nonbreeding. Subadults and nonbreeding adults remain at sea year-round, and disperse essentially throughout the North Pacific, south to around 20° N, and north into the Sea of Okhotsk and Bering Sea.

The majority of the population seems to gravitate to offshore waters of North America from British Columbia to Baja California, where it is present in numbers year-round.

A significant minority summers in Alaskan waters, including the Bering Sea, Aleutians, and Gulf of Alaska, mainly from July to October.

Another sizeable minority of the population is present year-round in Japanese waters, with a few regularly appearing west to Taiwan and likely also in the East China Sea.

Identification

A predominantly dark-brown albatross with a dark bill and black feet—usually the only bird of this description present in the North Pacific.

Its plumage is characteristically brown overall, but the shades and patterns vary greatly with age, feather-wear, sun-bleaching, and viewing conditions.

Juveniles are blackish-brown overall with a whitish fringe around the base of the bill. On older immatures and adults, the fringe around the base of the bill whitens and widens. They also have a white spot or patch below and behind the eye.

Adults tend to develop pale plumage elsewhere, but the patterns vary. Many turn pale-brown, then eventually white, on the belly. The bill also lightens from blackish to brown and sometimes becomes very pale.

Most, if not all, adults progressively develop contrasting whitish or all-white undertail coverts and rump. There are five numbered “stages”—from all-dark to >95% white—which appear to correlate to maturity, although the correlation might be imprecise and skewed by sex (more white on males).

The shade of brown over most of the plumage can vary from blackish to pale-blond and even white—especially on the head. Such bleaching can happen with both immatures and adults.

The uppersides of the wings are entirely brown, except that the primaries have bright white shafts.

The undersides of the wings are dark overall, but often to show paler or whitish flashes on the primaries and to a lesser extent on the secondaries and one or more rows of coverts.

Notes

Monotypic species.

IUCN Red List Status: Near Threatened.

See below for comparisons of Black-footed Albatross with Short-tailed, Sooty, and Light-mantled Albatrosses.

Cf. Immature Short-tailed Albatross. Black-footed is usually the only all-dark albatross present in most parts of the North Pacific, except for immatures of the rare but increasing Short-tailed Albatross. The difference is usually obvious, as Short-tailed is significantly larger and typically shows a bright, bubblegum-pink bill, whereas Black-footed’s bill is generally either black or some shade of brown.

In some cases, however, Short-tailed’s bill can be dull-pink and Black-footed’s bill tends to lighten with age, so the difference may not always be as conspicuous as field guide illustrations suggest.

Cf. Sooty and Light-mantled Albatrosses. Black-footed does not normally overlap with Sooty or Light-mantled Albatrosses so its potential for confusion with these species is limited to exceptional instances of long-distance vagrancy. All are predominantly dark including their bills and feet.

There are two fundamental differences: body shape and face coloration. Black-footed has a short tail and the bulk of its body is evenly distributed. In contrast, both Sooty and Light-mantled have long, pointed or wedge-shaped tails and a bull-necked, barrel-chested shape in flight.

Black-footed’s face is pale around the base of the bill—much less so in juveniles, but still palest beside the bill. In contrast, both Sooty and Light-mantled have all-dark faces which typically appear darkest near the bill.
