About These Birds
African River Martin
The African River Martin is a data-deficient swallow of the Hirundinidae family, with a wingspan of about 24 cm and a weight of 26 g. It is a poorly known species of the Congo River basin, roosting in vast numbers on sandy river islands during the dry season.
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.
