Albatross are known to be amongst some of the longest-lived birds and the black-browed can continue to breed up to an age of 35 years (4). Adults become mature at seven years old and, having found a mate, will pair for life (4). The birds usually return to the same nesting site each September and a single egg is laid the following month. The incubation period lasts nearly two months and the chick stays on the nest until late March or early April (4). Black-browed albatross feed on fish, squid, octopus and crustaceans but will also take floating carrion if they find it (5). Albatrosses are also known as 'Mollymawks' across much of their range (4).
