| 説明 | California Quail (Callipepla Californica)The California Quail is a highly sociable bird that often gathers in small flocks known as "coveys". One of their daily communal activities is a dust bath. A group of quail will select an area where the ground has been newly turned or is soft, and using their underbellies, will burrow downward into the soil some one to two inches. They then wriggle about in the indentations they have created, flapping their wings and ruffling their feathers, causing dust to rise in the air. They seem to prefer sunny places in which to create these dust baths, and an ornithologist is able to detect the presence of quail in an area by spotting the circular indentations left behind in the soft dirt, some 7–15 cm (3-6 inches) in diameter.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. They were originally found mainly in the southwestern United States but they have been introduced into other areas including British Columbia, Hawaii, Chile, New Zealand, and to Norfolk Island and King Island in Australia. These birds forage on the ground, often scratching at the soil. They can sometimes be seen feeding at the sides of roads. Their diet consists mainly of seeds and leaves, but they also eat some berries and insects; for example, Toyon berries are a common food source. If startled, these birds explode into short rapid flight, called "flushing". Given a choice, they will normally make their escape on foot.Taken by: WolfThis work is licensed under a Creative Commons Attribution-NoDerivs 3.0 Unported License. |
