Another photo of the bird showing the chestnut below, and black (doesn't show the white rump from this angle)

A bird, black with a white spot above its rump, perched on a stick.

It is a thrushlike bird with a long, graduated tail. Males are glossy black above and rich chestnut below. Females are similar but paler.
