Tawny-headed Swallows are unremarkable in appearance, with a small gray-brown body and a white abdomen, but have a distinctive deep reddish brown or tawny-rufous color on the forehead, eyebrow and back of the neck. The feathers of crown are almost black with reddish brown edges. The chin, throat, breast, and sides of the head (auriculars) are cinnamon-buff. It is found in open habitats near marshes, ponds, rivers, or streams. Tawny-headed Swallows are local in Venezuela, and have a more extensive distribution in central Bolivia and southern Brazil, south to northern Argentina. It tends to be a solitary species, and usually forages in pairs or in small groups that associate little with other swallow species. This species forages for insects during flight and flies close to the ground while swooping frequently. Breeding pairs of Tawny-headed Swallows nest alone or in small scattered groups, with nest usually in holes along river banks.
