Synoicus chinensis, commonly known as the King Quail or Blue-breasted Quail, inhabits grasslands and agricultural fields across Asia and Australia. These small birds exhibit sexual dimorphism, with males displaying striking blue-grey plumage and females having more subdued brown tones. They are ground-dwelling, foraging for seeds and insects, and are known for their rapid, low flights.

Synoicus chinensis, commonly known as the Blue-breasted Quail or Chinese Painted Quail, is native to Southeast Asia. Its geographical distribution includes countries like India, China, Indonesia, Malaysia, the Philippines, Thailand, and Vietnam. The species is also found in parts of Australia and the Pacific islands.

The Blue-breasted Quail typically inhabits grasslands, agricultural fields, and open woodlands. It favors areas with dense ground cover, which provides protection from predators and harsh weather conditions. The species thrives in warm, humid climates prevalent in tropical and subtropical regions.

As a ground-dwelling bird, Synoicus chinensis plays a role in seed dispersion and pest control within its ecosystem. It primarily feeds on seeds, small insects, and other invertebrates, contributing to the control of insect populations and aiding in the maintenance of plant diversity through seed dispersal.
