BEHAVIORS
The bank swallow is a common migrant and summer resident in Illinois. It winters in South America, as far south as Chile. The bank swallow lives in open areas, over fields, in marshes and along streams, lakes and ponds. It feeds on insects. Its call is "brrt" or "bjjt." This bird is colonial (stays in large groups). It has an unsteady flight pattern with irregular fluttering. Spring migrants begin arriving in Illinois in late March and April. Nesting occurs from May to July. Nests are placed in banks along waterways or roadways or in sand mounds. Nests are in colonies of 20 to 2,000 pairs. Nest cavities average two to three feet deep and contain three to seven white eggs. Fall migration begins by late July.
