The plumage of seabirds is thought in many cases to be for camouflage, both defensive (the colour of US Navy battleships is the same as that of Antarctic prions, [20] and in both cases it reduces visibility at sea) and aggressive (the white underside possessed by many seabirds helps hide them from prey below). The usually black wing tips help ...
The majority of procellariiforms nest once a year and do so seasonally. [69] Some tropical shearwaters, like the Christmas shearwater, are able to nest on cycles slightly shorter than a year, and the large great albatrosses (genus Diomedea) nest in alternate years (if successful). Most temperate and polar species nest over the spring-summer ...
Many seabirds remain at sea for several consecutive years at a time, without ever seeing land. Breeding is the central purpose for seabirds to visit land. The breeding period (courtship, copulation, and chick-rearing) is usually extremely protracted in many seabirds and may last over a year in some of the larger albatrosses ; [ 1 ] [ 2 ] this ...
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.
Where it nests on the tundra in the far north, the Arctic skua (Stercorarius parasiticus) is a terrestrial predator, but at lower latitudes, it is a specialised kleptoparasite, concentrating on auks and other seabirds. It harasses puffins while they are airborne, forcing them to drop their catch, which it then snatches up.
They frequent the breeding grounds of the islands in the Gulf of Mexico and the Caribbean Sea. With the rise in pollution in the world, brown boobies have been using marine debris to make their nests, with 90.1% of these nest were consisted of plastic, while nests near shipwreck have a high percentage of the wreckage debris.

Mice accidentally introduced to a remote island near Antarctica 200 years ago are breeding out of control because of climate change, and they are eating seabirds and causing major harm in a ...
The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters.This family is part of the bird order Procellariiformes (or tubenoses), which also includes the albatrosses and the storm petrels.
