Morphology and flight

Morphology and Flight

Albatrosses have a need to lower their salt content due to drinking sea water.

Albatrosses are colonial, nesting for the most part on remote oceanic islands, often with several species nesting together. Pair bonds between males and females form over several years, with the use of 'ritualised dances', and will last for the life of the pair.


Morphology and flight1

Morphology and Flight

Albatrosses range over huge areas of ocean and regularly circle the globe.

The wingspans of the largest great albatrosses are the largest of any bird, exceeding 340 cm (11.2 ft), although the other species' wingspans are considerably smaller (1.75 m (5.7 ft). The wings are stiff and cambered.

Threats and conservation

Threats and Conservation

In spite of often being accorded legendary status, albatrosses have not escaped either indirect or direct pressure from humans.

Of the 21 albatross species recognised by World Conservation Union 19 are threatened, and the other two are near threatened. Two species (as recognised by the World Conservation Union) are considered critically endangered: the Amsterdam Albatross and the Chatham Albatross.

Threats and Conservation

  • Fact Box

  • Fishing kills thousands of albatross every year

  • The birds get hooked and drown

  • Albatross face extinction if this doesn’t stop


Threats and conservation2

Threats and Conservation

  • Longlining

Albatrosses are attracted to the squid or fish used as bait. As the baited hooks are thrown into the water the birds dive down and swallow them. Then they are dragged down on the long line and drowned.


Threats and conservation3

Threats and Conservation

  • Trawlingseabirds are being killed in trawl fisheries, either by entanglement in nets, or collisions

  • Plastic debris

Albatrosses frequently feed on dead squid and fish eggs that float on the sea's surface. Floating plastic objects are often mistaken for food and swallowed, causing blockages and reducing the amount of food that can be eaten.


Threats and conservation4

Threats and Conservation

Agreement on the Conservation of Albatrosses and Petrels (ACAP)

The treaty requires countries member to take specific actions to reduce by-catch, pollution and to remove introduced species from nesting islands.
