This bird has round chunky body and is easily recognizable due to the plume on its head. Plume of males is dark and thick. Also, males possess black patch on their breast as well as black neck and face. Plume of females, however, is duller and thinner. In addition, unlike males, female quails do not have black markings on their breast. The plumage or mature males is more vivid than that of females. The Gambel's quail has white and cream-colored markings throughout the body. The wings are olive-colored and the sides are chestnut. Various populations of this species may differ in plumage coloration. Thus, quails, living in more rainy areas, are somehow darker, having more striking plumage.
The Gambel's quail is distributed throughout the southwestern United States, primarily in Arizona. This bird is also found in Texas, California as well as southern Utah, Nevada and Colorado. The area of its distribution includes also some parts of Mexico. Their major habitat is brushy riparian woodland and arid desert scrub. The Gambel’s quail inhabits wide variety of desert such as low warm deserts with mesquite, upland warm deserts with Acacia, yuccas and cactus as well as cool deserts with sagebrush.
Gambel’s quails are diurnal animals. On the sunset, they find a suitable place to roost in groups. They prefer safe areas with dense cover such as shrubs or trees in order to protect themselves against predators and cold winds. These birds are social animals with unique social system. They mate during the spring months meanwhile being aggressive towards other couples. By the end of the breeding season, they regroup, forming coveys - flocks that may contain up to 25 individuals depending on climatic condition. During the time of living in coveys, they become very calm, showing highly social behavior and foraging together for food.
These birds are monogamous, mating once in a breeding season, though there have been known cases of a female, leaving its mate and chicks for another male. During the breeding season, which lasts from April to July, male quails try to attract females, using various methods. Female has to build the nest, which is a simple spot on the ground, usually covered by rocks and plants. When the nesting site is chosen, she defines it with grass, sticks and leaves. Then she lays 12 eggs at a brood. The eggs are incubated for 20-24 days. Young are able to move as soon as they are hatched out. The chicks learn how to forage and find food, observing their parents. Sexual maturity is reached at 1 year old with male quails, becoming mature a few weeks earlier than females.
One of the notable threats to this bird is degradation of its habitat due to urban development. On the other hand, the chicks are threatened by rising temperatures within their range, which is a result of pollution and global warming. Another threat is predators - both aerial and terrestrial. In addition, cattle grazing in the area of their habitat is among other concerns to this species’ population.
Although the exact number of their population is presently unknown, this widespread species is not endangered and is classified on the IUCN Red List as Least Concern (LC).
These birds play important role in the ecosystem. Feeding upon various plants, Gambel's quails disperse seeds of these plant species. They are also an important source of food for predators of their range.
