Seabirds and humans have a long history together: They have provided food to hunters, guided fishermen to fishing stocks, and led sailors to land. Many species are currently threatened by human activities such as oil spills, nets, climate change and severe weather.
Climate change may well affect populations of seabirds in the northern Atlantic. The most important demographic may be an increase in the sea surface temperature, which may have benefits for some northerly Atlantic puffin colonies. [58] Breeding success depends on ample supplies of food at the time of maximum demand, as the chick grows.
They nest in burrows and often give eerie contact calls on their night-time visits. They lay a single white egg. They lay a single white egg. The chicks of some species, notably short-tailed and sooty shearwaters, are subject to harvesting from their nest burrows for food, a practice known as muttonbirding , in Australia and New Zealand.
Frigatebirds are referred to as kleptoparasites as they occasionally rob other seabirds for food, and are known to snatch seabird chicks from the nest. Seasonally monogamous, frigatebirds nest colonially. A rough nest is constructed in low trees or on the ground on remote islands. A single egg is laid each breeding season.
Due to its size, aggressive nature and fierce defence of its nest, the great skua has little to fear from other predators. While fledglings can fall prey to rats , cats or the Arctic fox , healthy adults are threatened only by greater raptors such as the golden eagle , the white-tailed eagle , and more rarely, at sea by the orca .

[4] The former name was also used by the English naturalist Francis Willughby in the 17th century; the species was known to him from a colony in the Firth of Forth and from a stray bird that was found near Coleshill, Warwickshire.

The short-tailed shearwater or slender-billed shearwater (Ardenna tenuirostris; formerly Puffinus tenuirostris), also called yolla or moonbird, and commonly known as the muttonbird in Australia, is the most abundant seabird species in Australian waters, and is one of the few ...
