White-throated Treerunner

Open encyclopedia reference

The white-throated treerunner (Pygarrhichas albogularis) is a species of bird in the family Furnariidae. It is the only species in the genus Pygarrhichas. The white-throated treerunner is about 15 cm (5.9 in) long, with a stiff and rounded tail. The upperparts are dark brown, turning red on the lower back and tail and contrasting sharply with the throat and chest of a bright white. The rest of the underparts are coarsely mottled with white. The bill is long, slightly curved upwards. The general appearance is reminiscent of a nuthatch (Sitta spp.), although they are not directly related. Like the Sittidae, Furnariidae tirelessly scours the trunks and branches of old trees for the small arthropods that make up its food, spiraling up the trunks, or sometimes moving head down. The white-throated treerunner consumes small invertebrates found on bark and nests in tree cavities. Outside of the breeding season, it may form mixed-species foraging flocks with other bird species.
