The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. Seabirds generally live longer, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in colonies, varying in size from a few
Northern giant petrels forage in similar locations to southern giant petrels, but at different times due to the earlier breeding season of northern giant petrels. It is thought this temporal segregation in habitat-use reduces interspecific competition, whilst sexual segregation, due to females making more pelagic trips than males, reduces ...
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 nest is a cleared area 0.75 to 1 m (2 ft 6 in to 3 ft 3 in) in diameter, within which is a clearly demarcated 25 to 30 cm (10 to 12 in) shallow (1–2 cm (0.4–0.8 in) deep) depression. A clutch of two chalky white eggs is laid, with an interval of five to eight days between the laying of each egg.
The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. [4] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

The nest tunnel is 10–300 cm (3.9–118.1 in) long and 5–8 cm (2.0–3.1 in) across, with a slightly narrower entrance. The nest chamber is typically unlined, although pairs may bring in some grass, bracken, or seaweed. Although the storm petrel is generally not territorial when breeding, a pair defends the nest chamber itself after the ...
