About These Birds

Yap Monarch

Black-chinned Monarch

The Black-chinned Monarch is a Critically Endangered small flycatcher known only from a tiny area on Boano Island in the Maluku province of Indonesia. Its very restricted range—a single small island—and potential habitat loss make it one of the world's most threatened monarchs. It inhabits forest interior and edges, feeding on insects. Very little is known about its ecology due to limited study.
