The typical migration through, and residence and breeding of these birds at Presqu'ile provincial park, roughly 40 km to the south, occurs from mid-April to late September, with extreme sightings on 13 April and 16 November (LaForest, 1993, pp.251-252). Birds seen in the park after mid-May are part of the local breeding population, while fall migrants move through from late July to late September. In Peterborough county, to the northwest, the barn swallow has been noted from 03 April to 05 October (Sadler, 1983, pp.112,177).
