At Presqu'ile provincial park, roughly 40 km to the south, the eastern pewee is a common migrant and summer breeding resident, from mid-May to late September (LaForest, 1993, p.234). In Peterborough county, to the northwest, the pewee is typically found between 1 May and 3 September (Sadler, 1983, p.106).
The pewee (Cadman et al., 1987, pp.252-253) is, like the phoebe, a relatively common flycatcher in southern Ontario. Woodland clearances have increased suitable habitat. In the revised Bird Breeding Atlas (Cadman et al., 2007, pp.340-341) the pewee is widely found across our region, from southern Georgian Bay east to the Frontenac arch. It prefers forest margin settings.
