Light-mantled Albatross (Phoebetria palpebrata) [Forster, 1785]

Taxonomy

Forms a species pair with the Sooty Albatross, and in the South Atlantic nest on the same islands. Some times kown as ‘Blue Bird’, a named used by 19th Centuary sealers because it looked blue in strong Antarctic light.

Identification

Arguably the most beautiful albatross. In flight, has a distinctive cruciform-like shape created by the combination of thin wings, long tail and long neck. This is evident at great distances and on high soaring birds. The wings are thinner than other albatrosses and can be useful in spotting distant birds in poor light conditions or fog. The wings are usually held slightly bowed in flight, again a useful feature in birds approaching or going away from the boat.

Light-mantled Sooty Albatross is highly acrobatic and pairs will use ships as an impromptu display ground, riding the updrafts created by the ships passage (per. obs). Sometimes it seems as if rival males will try to impress a female with their skills at mirroring her movements. Will also give an eery call if flight.

The most likely confusion is with closely-related Sooty Albatross which lacks the pale mantle and has a blue-white rather than creamy-orange line (sulcus) along the cutting edge of the bill.
 

Where and When

World population estimated at 150,000 individuals with some 25,000 breeding pairs.  Approximately 1000 pairs nest on Australia's Macquarie Island and there are up to 4000 pairs on South Georgia.  Breed every other year. The species is suffering heavily from long-line fishing.

More of a ship follower than Sooty Albatross. Most often seen near accessible breeding islands such as South Georgia or around the Subantarctic Islands of New Zealand. Possible in the Humbolt Current off South America, perhaps explaining the remarkable record from the Cordell Bank, California on 17 July 1994 (Stallcup and Terrill, 1996).
