Rueck's Niltava

The Rueck's Blue-flycatcher is endemic to the island of Sumatra, Indonesia. It is known only from four specimens. Two specimens, an immature and adult male were last recorded and collected around 1917-1918 in secondary lowland forests in Medan area of North Sumatra province by the Dutch collector, August van Heijst. The other two skins are of doubtful origin.

The Rueck's Niltava is classified as Critically Endangered (CR), facing an extremely high risk of extinction in the wild.
