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 ...
The pintado petrel (Daption capense), also called the Cape petrel, Cape pigeon or Cape fulmar, [2] is a common seabird of the Southern Ocean from the family Procellariidae. It is the only member of the genus Daption, and is allied to the fulmarine petrels, and the giant petrels. They are extremely common seabirds with an estimated population of ...
The first seabirds evolved in the Cretaceous period, while 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
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.
Furthermore, it has been proposed that birds that nest in high densities, as seabirds do in breeding colonies, have higher rates of EPCs and EPFs than birds that do not nest colonially. [46] Despite this, Westneat and Sherman (1997) [49] found no significant correlation between nesting density and EPFs in a meta-analysis. Many seabird species ...
Calonectris is a genus of seabirds.The genus name comes from Ancient Greek kalos, "good" and nectris, "swimmer".. The genus comprises four large shearwaters.There are two other shearwater genera, Puffinus, which comprises 21 small to medium-sized shearwaters, and Ardenna with 7 larger species.

Cory's shearwater (Calonectris borealis) is a large shearwater in the seabird family Procellariidae. It breeds colonially on the archipelago of the Azores in the eastern Atlantic. Outside the breeding season it ranges widely in the Atlantic. It was formerly considered to be conspecific with Scopoli's shearwater.
