Black-browed albatross
The most widespread and common albatross species.
The black-browed albatross (Thalassarche melanophris), also known as the black-browed mollymawk, is a large seabird of the albatross family Diomedeidae. It is the most widespread and common member of its family, found circumpolar in the southern oceans and breeding on 12 islands. First described by Coenraad Jacob Temminck in 1828 based on a specimen from the Cape of Good Hope, its name derives from Greek words meaning 'black eyebrow,' referring to the dark feathering around its eyes.

Lore & Background
The black-browed albatross is a medium-sized albatross with a dark grey saddle and upperwings contrasting with white underparts. It has a distinctive dark eyebrow and a yellow-orange bill with a darker reddish-orange tip. Juveniles have dark horn-colored bills and a grey head and collar. The species is distinguished from other mollymawks by its dark eyestripe, broad black edging to the white underside of its wings, white head, and orange bill. The closely related Campbell albatross is very similar but has a pale eye.
Reader's Guide
The black-browed albatross is the most widespread and common member of the albatross family, with an estimated 1,220,000 birds alive as of 2005. It breeds on 12 islands across the southern oceans, including the Falkland Islands, South Georgia, and the Crozet Islands. The species has experienced a 67% decline in population over 64 years, leading to its classification as endangered by the IUCN until 2013. Major threats include longline and trawl fishing, particularly around the Patagonian Shelf and South Georgia. Conservation efforts include monitoring on half of its breeding islands, protection of most breeding sites as reserves, and inclusion in international agreements such as the Convention on Migratory Species Appendix II and the Agreement on the Conservation of Albatrosses and Petrels Annex 1. The species is also notable for its vagrancy, with individuals occasionally summering in Scottish and Faroese gannet colonies, and one individual named Albert has been sighted repeatedly in the North Atlantic.
