The genus Sula was introduced by the French zoologist Mathurin Jacques Brisson in 1760. [3] The type species is the brown booby. [4] The name is derived from súla, the Old Norse and Icelandic word for the other member of the family Sulidae, the gannet.
Seabird eggs have also long been an important source of food for sailors undertaking long sea voyages, as well as being taken when settlements grow in areas near a colony. Eggers from San Francisco took almost half a million eggs a year from the Farallon Islands in the mid-19th century, a period in the islands' history from which the seabird ...
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.
The red-footed booby (Sula sula) is a large seabird of the booby family, Sulidae.Adults always have red feet, but the colour of the plumage varies. They are powerful and agile fliers, but they are clumsy in takeoffs and landings.
However, razorbills are slightly more agile. In North America it is a largely migratory seabird, as during the colder months, it leaves land and spends the entire winter in the waters of the Atlantic Ocean, [34] though western European birds often remain close to their breeding sites. During breeding, both males and females protect the nest.
The Grange Insurance Audubon Center is located near the western edge of the park, at 505 W. Whittier St. The 18,000 sq ft (1,700 m 2) building is the first Audubon center built in close proximity to a downtown area. It was built along with the park, opening in August 2009 at a cost of $14.5 million.
The skuas / ˈ s k juː ə / are a group of predatory seabirds with seven species forming the genus Stercorarius, the only genus in the family Stercorariidae.The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.
The nest is a cleared area 0.75 to 1 m (2 ft 6 in to 3 ft 3 in) in diameter, within which is a clearly demarcated 25 to 30 cm (10 to 12 in) shallow (1–2 cm (0.4–0.8 in) deep) depression. A clutch of two chalky white eggs is laid, with an interval of five to eight days between the laying of each egg.
