栗小鷺〔栗葦鳽〕

The cinnamon bittern (Ixobrychus cinnamomeus) is a small heron in the family Ardeidae, widely distributed across South and Southeast Asia, from Pakistan and India east through Southeast Asia to China, Japan, and the Philippines, south through Indonesia and Papua New Guinea. It inhabits wetlands including rice paddies, reedbeds, marshy grasslands, and the margins of ponds and rivers, where it stalks prey in dense emergent vegetation. The plumage is entirely cinnamon-brown in males, while females are more streaked. Like other small bitterns, it has a cryptic freezing posture—stretching its neck vertically to blend with reeds—when alarmed. The cinnamon bittern is classified as Least Concern by the IUCN, with a widespread and abundant Asian distribution. It is entirely absent from Europe; database records citing Norway are data artifacts. This species is highly tolerant of rice cultivation and degraded wetlands, making it one of the more adaptable Asian herons. However, wetland loss from drainage and intensification of rice agriculture across South and Southeast Asia poses long-term threats to wetland species broadly. The cinnamon bittern is a shy and secretive bird that is more often heard—giving a deep, booming call—than seen in its dense wetland habitat.
