Campina thrush

The Campina thrush (Turdus arthuri) is a thrush in the genus Turdus native to the Amazon biome. It was previously considered conspecific with the black-billed thrush.

Taxonomy
The Campina thrush was originally described by Charles Chubb as Arthur's thrush in 1914 from a specimen taken near the Abary River in British Guiana (modern day Guyana), and placed in the genus Planesticus. It was considered a subspecies of black-billed thrush until 2019 when a proposal to split it and the Pantepui thrush was unanimously approved by the South American Classification Committee.

Description
The Campina thrush has a total length of 202mm and a weight of 64g. It is a medium-sized dusky brown thrush, with a white throat with brown streaks. It has a white vent and undertail and a pale belly. It looks similar to its relative the Pantepui thrush, but is smaller with a slight olive wash on its wings and a generally more ashy appearance.

Distribution and habitat
The species is the most common Turdus thrush of disturbed habitats in west central Amazonia and on the Guianan Shield, occurring in Brazil, Guyana, Suriname, and Venezuela. It inhabits a variety of habitats including clearings, savannas with gallery woodland, cerrado, humid forest borders, coffee plantations, and various other habitats under anthropogenic influence.
