The Lemon-rumped Tanager inhabits the lowland regions of western Colombia, Ecuador, and parts of Panama, thriving in semi-open forests, woodland edges, and areas of secondary growth. This species is commonly observed in pairs or small groups, often joining mixed-species flocks, and is known for its distinctive vocalizations, which include a series of sharp, metallic notes. The male displays a striking black plumage contrasted by a bright yellow rump, while the female exhibits a more subdued coloration with olive-brown upperparts and yellowish underparts. The Lemon-rumped Tanager is considered abundant within its range and is frequently found in urban and suburban gardens. Its diet primarily consists of fruits and insects, playing a role in seed dispersal within its ecosystem.
