Areale e habitat

The recurve-billed bushbird is known from a few sites in Venezuela's Sierra de Perijá and in the Colombian departments of Antioquia, Norte de Santander, and Santander. It was formerly much more widespread. The species inhabits dense undergrowth in the understory and edges of evergreen forest, clearings in the forest that are regenerating, and nearby secondary forest. In one Colombian area it is associated with bamboo. In elevation it ranges between 300 and 1,200 m (1,000 and 3,900 ft) in Venezuela. In Colombia it is mostly found between 200 and 1,000 m (700 and 3,300 ft) but occurs as high as 1,150 m (3,800 ft).
