Colonial seabirds in Hawaii. Great Frigatebirds, Black Noddies and Red-footed Boobies nest on the bushes whilst Red-tailed Tropicbirds and Sooty Terns nest on the ground around and underneath them.

A seabird colony is a site which seabirds visit to breed. Although some colonies are small, classic seabird colonies contain hundreds or thousands of birds (some colonies of over a million birds are known). Colonies are usually at coastal locations (e.g. cliffs, lagoons, islands, beaches), although some birds traditionally regarded as seabirds have spread and founded colonies inland. In addition, some nocturnal petrels and shearwaters nest inland on mountains or cliffs.

Individual nesting sites at seabird colonies can be widely spaced, as in an albatross colony, or densely packed like an auk colony. 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. Genera Diomedea Thalassarche Phoebastria Phoebetria Albatrosses, of the biological family Diomedeidae, are large seabirds allied to the procellariids, storm-petrels and diving-petrels in the order Procellariiformes (the tubenoses). ...

The species makeup of a seabird colony depends on its topography and geography. Cliff colonies in northern latitudes are usually dominated by auks. Particularly large colonies of this type occur in the north Atlantic, such as in Britain, Ireland, Norway and Iceland; and in the north Pacific, particularly Alaska. Colonies on tropical islets are usually dominated by terns, for example at the Dry Tortugas.

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. This increases breeding success, provides a place for returning mates to reunite, and reduces the costs of prospecting for a new site. Young adults breeding for the first time usually return to their natal colony, and often nest very close to where they hatched. For the financial services company, see Fidelity Investments. ...


Colonies are thought to provide protection to seabirds, which are often very clumsy on land, and are usually situated in places where land mammals have difficulty getting to. I smoke weed im growing a blue penis dude#REDIRECT penises are cool ...


See List of seabird colonies, Seabird Colony Register The Seabird Colony Register (SCR) is a database, managed by the British Joint Nature Conservation Committee, which contains counts of breeding seabirds at British seabird colonies made between 1969 and 1998, which is used for analysing past changes in breeding seabird numbers in Britain and Ireland. ...

Seabird - Wikipedia, the free encyclopedia (4223 words)
Seabirds, by virtue of living in a geologically depositional environment (that is, in the sea where sediments are readily laid down) are well represented in the fossil record.
Coloniality often arises in other types of bird which do not defend feeding territories (such as swifts, which have a very variable prey source), this may be a reason why it arises more frequently in seabirds.
Seabirds, being apex predators, suffered from the ravages of DDT until they were banned, and concern continues with other pollutants, for example Forster's Terns in San Francisco were found to have high levels of polybrominated diphenyl ethers (PBDEs), used as fire retardants.

Seabird colony surveys conducted along the BC coast during the mid-1970s by the BC Provincial Museum identified colony sites and provided rough estimates of breeding birds, which can be used to detect only very large changes in nesting distribution and population size.
However, changes at colonies where rats and raccoons have been, or still are, present were all negative, with annual rates of decrease ranging from -1 to -23% (Table 3).
Trends based on colony censuses on Reef and East Limestone islands were very similar to those based on chick departures monitored annually at the same colonies, suggesting an increase of approximately 40% between 1985 and 1995 on Reef Island and an approximate decrease of 25% between 1989 and 1995 on East Limestone Island (Fig.
