The sooty thrush (Turdus nigrescens) is a large thrush endemic to the highlands of Costa Rica and western Panama. It was formerly known as the sooty robin. This is an abundant bird of open areas and oak forest edge normally above 2200 m altitude. It builds a heavy grass-lined cup nest in a tree 2–8 m above the ground, and the female lays two unmarked greenish-blue eggs between March and May. Two superficially similar relatives share this species' range. The mountain thrush is uniformly brown with dark bare parts, and the clay-colored robin is much paler and yellow-billed.
