Alternative name: Sooty Mollymawk
- Phoebetria fusca
Identification
Length: 84-89cm (33-35 in). Wingspan: 195-205cm.
One of the two Phoebetria species which are distinguished from Diomedea albatrosses by wholly sooty-brown plumage, very slender wings and pointed tail, and more graceful, bouyant wheeling flight but very difficult to tell apart.
Adult: sooty-brown slightly darker on head, particularly on sides and paler across nape, tail and primaries blackish with pale shaft-streaks. Iris brown, incomplete white eye-ring, bill black with yellow or orange stripe on lower mandible and legs greyish or mauve.
Immature: juvenile as adult but with paler nape sometimes forming half-collar and indistinct paler fringes to mantle. Bill blackish with grey, bluish or purple stripe on lower mandible and lacks white shaft-streaks on tail and primaries.
Similar Species
Light-mantled Albatross - has paler upperparts extending from hindneck to rump contrasting with wings and at close range by blue stripe on lower mandible.
Immatures can be very difficult to separate as colour of bill-stripe can overlap but pale plumage above on Sooty does not extend to lower back and rump as in Light-mantled Albatross.
Distribution
South Atlantic and southern Indian Oceans. Breeds on Tristan da Cunha and Gough Island in the Atlantic and in the Indian Ocean on Amsterdam, St Paul, Marion, Prince Edward, Crozet and Kerguelen Islands. Dispersing birds occur throughout the southern Atlantic and Indian Oceans between about 300S and 600S.
Uncommon off Australia and South Africa and not recorded in New Zealand waters
