The black noddy (Anous minutus), also known as white-capped noddy, is a species of tern in the family Laridae.It is a medium-sized seabird with black plumage and a white cap that closely resembles the lesser noddy with which it was at one time considered conspecific.
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.
The great frigatebird (Fregata minor) is a large seabird in the frigatebird family.There are major nesting populations in the tropical Pacific Ocean, such as Hawaii and the Galápagos Islands; in the Indian Ocean, colonies can be found in the Seychelles (on Aldabra and Aride Islands) and Mauritius, and there is a tiny population in the South Atlantic, mostly on and around St. Helena and ...
In most seabird colonies several different species will nest on the same colony, often exhibiting some niche separation. Seabirds can nest in trees (if any are available), on the ground (with or without nests), on cliffs, in burrows under the ground and in rocky crevices. Colony size is a major aspect of the social environment of colonial birds.
Some of the larger petrels have to nest on windswept locations as they require wind to take off and forage for food. [27] Within the colonies, pairs defend usually small territories (the giant petrels and some albatrosses can have very large territories) which is the small area around either the nest or a burrow.
The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean.
Seabird eggs have also long been an important source of food for sailors undertaking long sea voyages, as well as being taken when settlements grow in areas near a colony. Eggers from San Francisco took almost half a million eggs a year from the Farallon Islands in the mid-19th century, a period in the islands' history from which the seabird ...
The southern giant petrel measures 86 to 99 cm (34–39 in) with a wingspan of 185 to 205 cm (6 ft 1 in – 6 ft 9 in). Both this and the northern giant petrel vary considerably in size, with southern colonies averaging larger than northern colonies, in line with Bergmann's rule. Due to the large amount of size variability, it is difficult to ...
