The California quail is the official state bird of California. 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.
The South Bay California gull population has grown from less than 1,000 breeding birds in 1982 to over 33,000 in 2006. This population boom has resulted in large resident flocks of gulls that will opportunistically prey on other species, particularly the eggs and nestlings of other birds.
For species found in the 50 states, Puerto Rico, and the U.S. Virgin Islands, the taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the list are those of the AOS, the recognized scientific authority on the taxonomy and nomenclature of North and Middle American birds.
The genus name means "raven-vulture", [12] from a contraction of the Greek corax/κόραξ and gyps/γὺψ for the respective birds. [13] The American Ornithologists' Union used the name Catharista atrata initially before adopting Vieillot's name (Catharista urubu) in their third edition. [14] By their fourth edition, they had adopted the ...
The Pacific Flyway is a major north-south flyway for migratory birds in the Americas, extending from Alaska to Patagonia. [1] Every year, migratory birds travel some or all of this distance both in spring and in fall, following food sources, heading to breeding grounds, or travelling to overwintering sites. [2]
The coastal populations consist of both migratory and residential birds; migration occurs over relatively short distances north- or southward along the coast. Inland breeding populations exist in the US eastward to the Great Plains of Kansas and Oklahoma, as well as in Mexico north of Mexico City. These populations are mostly migratory, with ...
The California quail (Callipepla californica), also known as the California valley quail or Valley quail, is a small ground-dwelling bird in the New World quail family. These birds have a curving crest, plume or topknot made of six feathers, that droops forward: black in males and brown in females; the flanks are brown with white streaks. Males ...
The flyways can be thought of as wide arterial highways to which the migratory routes of different species are tributaries. [1] An alternative definition is that a flyway is the entire range of a migratory bird, encompassing both its breeding and non-breeding grounds, and the resting and feeding locations it uses while migrating.
