Seabird breeding behavior
The term seabird is used for many families of birds in several orders that spend the majority of their lives at sea. Seabirds make up some, if not all, of the families in the following orders: Procellariiformes, Sphenisciformes, Pelecaniformes, and Charadriiformes. Many seabirds remain at sea for several consecutive years at a time, without ever seeing land. Breeding is the central purpose for seabirds to visit land. The breeding period (courtship, copulation, and chick-rearing) is usually extremely protracted in many seabirds and may last over a year in some of the larger albatrosses;〔Carboneras, C. 1992. "Family Diomedeidae (Albatross)" in Handbook of Birds of the World Vol. 1. Barcelona: Lynx Editions.〕〔Brooke, M. 2004. Albatrosses And Petrels Across The World. Oxford University Press, Oxford, UK.〕 this is in stark contrast with passerine birds. Seabirds nest in single or mixed-species colonies of varying densities, mainly on offshore islands devoid of terrestrial predators.〔Schreiber, Elizabeth A. and Burger, Joanne. 2001. Biology of Marine Birds. CRC Press, Boca Raton, Florida.〕 However, seabirds exhibit many unusual breeding behaviors during all stages of the reproductive cycle that are not extensively reported outside of the primary scientific literature.
==Courtship stage==
The courtship stage of breeding is when pair bonds are formed and occurs before copulation and occasionally continues through the copulatory and chick-rearing stages of the breeding phenology. The sequence and variety of courting behaviors vary widely among species, but they typically begin with territorial defense, followed by mate-attraction displays, and selection of a nest site.〔Alcock, J. 2004. Understanding bird behavior, p. 6-1–6-98. In S. Podulka, R. W. Rohrbaugh, and R. Bonney (), Handbook of Bird Biology. Princeton University Press, Princeton, NJ.〕 Seabirds are long-lived, socially monogamous, birds that usually mate for life. This makes selecting a mate extremely important with lifelong implications for the reproductive success of both individuals in the pair.
