The killdeer is a common migrant (mid-March to mid-April, and
late July to early November)
at Presqu'ile provincial park, roughly
40 km to the south, and breeds in the park: it is a common
summer resident. It has been seen in the park as early as
29 February, and as late as 02 December, with
an average departure date in mid-November
(LaForest, 1993, p.130).
In Peterborough county, to the northwest, the killdeer
has been noted as early as 29 February and as late as
07 November, but a few probably overwinter in the county
(Sadler, 1983, p.74).
