Quail
Coturnix coturnix
The quail listed as Coturnix coturnix is the common or European quail, a small migratory gamebird of grasslands, cereal fields, and open scrub across Europe, North Africa, and western Asia. Its mottled brown plumage hides it well on the ground, and males are often detected by their rhythmic call before they are seen. Common quail are close relatives of Japanese quail, Coturnix japonica, the species most often domesticated for eggs, meat, research, and small-scale aviaries. The two names are sometimes confused in sales listings under the broad label coturnix quail.
Kept quail need management more like ground birds than cage songbirds: low-stress housing, secure sides and tops, dry litter, places to hide, and protection from rodents and predators. Laying and grow-out birds are typically fed gamebird or turkey-style rations with higher protein than chicken layer feed, plus clean water in shallow or spill-resistant drinkers. They mature quickly and can be productive, but crowding leads to feather picking and injuries. Anyone buying eggs or breeding stock should confirm the species and local rules, especially where release of nonnative or captive gamebirds is regulated.
