The black-crowned barwing (Actinodura sodangorum) is a non-migratory bird from Indochina in the family Leiothrichidae (laughingthrushes and allies).

[2] The name Actinodura is derived from Greek words meaning "ray-like tail" (actinodes and ura) while sodangorum came from the Södang tribe (also known as Xo Dang) which lives in Ngoc Linh and other areas in Vietnam, Cambodia and Laos where black-crowned barwings are distributed.

Many observations were made by Jonathon Charles Eames and Roland Eve, but took until 17 March 1998 to trap a male bird.

[4] The posterior parts of the body (mantle, back, rump, and uppertail coverts) are olive-brown with indistinct dark bars.

They are also found in Important Bird and Biodiversity Areas (IBA) including the DakChung Plateau, Lo Xo Pass, and Ngoc Linh.

[3] The minimum elevation range could not be determined properly since the site contained loss of forest habitat below 1500m, though there were sightings at 1000m.

[8] The male displays by raising his crest and half-fanning his feathers while the female opens her wings less frequently and leans steeply over her perch.
