BEHAVIORS
Chuck-will’s-widow is an uncommon migrant and summer resident statewide in Illinois. It winters from the southern United States to Columbia, South America. Spring migrants begin arriving in Illinois in late March or early April. Two white eggs with gray or purple blotches and brown spots are laid on leaves or pine needles on the ground, with no nest built. Both sexes take turns incubating during the 20-day incubation period. Fall migration begins in September. This nocturnal bird may be found in both oak and pine forests, forest edges, upland areas and river woodlands. Its call is “Chuck-will’s widow,” which is how it got its common name. The first syllable of the call is often hard for humans to hear. It eats insects that it catches while flying and occasionally a small bird. Habitat destruction and degradation have led to the decline of this species in Illinois.
