Seabirds, along with some Australian and Southern African landbirds such as the southern ground hornbill [72] or white-winged chough, [73] have the longest chick-rearing stage of any bird on earth. [1] It is not unusual for many seabirds to spend 3–4 months raising their chicks until they are able to fledge and forage independently.
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. Competition can be strong both within species and between species, with aggressive species such as sooty terns pushing less dominant species out of the most desirable nesting spaces. [ 55 ]
Marbled murrelets are semicolonial in nesting habits. Two nests found in Washington were located only 150 feet (46 m) apart. Not all mature adults nest every year. [13] The clutch is a single egg. The nestlings fledge in 28 days. The young remain in the nest longer than other alcids and molt into their juvenile plumage before leaving the nest. [12]

This list of birds of California is a comprehensive listing of all the bird species seen naturally in the U.S. state of California as determined by the California Bird Records Committee (CBRC). [1] Additional accidental and hypothetical species have been added from different sources.
Birds ringed as chicks have been recaptured close to their original nests, sometimes extremely close; in the Laysan albatross the average distance between hatching site and the site where a bird established its own territory was 22 m (72 ft), [58] and a study of Cory's shearwaters nesting near Corsica found that nine out of 61 male chicks that ...
Approximately 13% of all bird species nest colonially. [2] Nesting colonies are very common among seabirds on cliffs and islands. Nearly 95% of seabirds are colonial, [3] leading to the usage, seabird colony, sometimes called a rookery. Many species of terns nest in colonies on the ground.

Castle Rock remained in private ownership until 1979, [3] when the United States Fish and Wildlife Service purchased it from The Nature Conservancy to conserve habitat for marine mammals and seabirds.
