The Chuck-will's-widow has been documented rarely but repeatedly at specific sites in southern Ontario. More often heard than seen, the secretive nature of this nocturnal aerial insectivore means that it may be overlooked even when present. Its core breeding range is in the central and southern portions of the eastern United States, while the wintering range extends from southern Texas to northern South America and the Caribbean. Although the Canadian population is likely larger than it was in the 1970s, no estimate is available and it is insufficiently monitored to evaluate the status of the species in Canada.
