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.
Many seabirds show remarkable site fidelity, returning to the same burrow, nest or site for many years, and they will defend that site from rivals with great vigour. [3] This increases breeding success, provides a place for returning mates to reunite, and reduces the costs of prospecting for a new site. [ 57 ]

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.
Marbled Murrelet (Brachyramphus marmoratus) showing winter plumage. Marbled murrelet winter habitat is the same as the nesting and foraging habitat. During the winter marbled murrelets use inland old-growth or mature sites for roosting, courtship, and investigating nest sites.
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 ...
A few species nest in small or dispersed groups, but most breed in colonies of up to a few hundred pairs, often alongside other seabirds such as gulls or skimmers. [5] Large tern species tend to form larger colonies, [ 18 ] which in the case of the sooty tern can contain up to two million pairs.
