About These Birds
Black-collared Swallow
The Black-collared Swallow is a distinctive South American swallow with glossy blue-black upperparts, white underparts, and a broad black collar across the upper breast. It inhabits rocky rivers and fast-flowing streams in lowland tropical forests and adjacent areas from Colombia and Venezuela south through Amazonian Brazil, often nesting in crevices of riverside rocks. It feeds on flying insects caught over water.
