These are small or medium-sized swallows, ranging from 11–17 cm in length. They are brown above and mainly white below, and all have a dark breast band.

These species are closely associated with water. They nest in tunnels usually excavated by the birds themselves in a natural sand bank or earth mound. They lay white eggs, which are incubated by both parents, in a nest of straw, grass and feathers in a chamber at the end of the burrow. Some species breed colonially.

The cosmopolitan Sand Martin is almost completely migratory
