What is the name of this beautiful bird?

The California quail, 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 or plume, made of six feathers, that droops forward: black in males and brown in females; the flanks are brown with white streaks. Males have a dark brown cap and a black face with a brown back, a grey-blue chest, and a light brown belly. Females and immature birds are mainly grey-brown with light-colored bellies.

The California quail is a highly sociable bird that often gathers in small flocks known as "coveys". They are year-round residents. Although this bird coexists well at the edges of urban areas, it is declining in some areas as human populations increase. Their breeding habitats are shrubby areas and open woodlands. This quail is the state bird of California. It was established as the state bird in 1932.
