Black-and-rufous Swallow
The Black-and-rufous Swallow is a distinctive swallow of the miombo woodland and open areas in East and Central Africa. It has glossy black upperparts and rich rufous-chestnut underparts and throat. It feeds on aerial insects, hawking over open woodland and water, and breeds in small colonies.

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.
