Common Grackle (Quiscalus quiscula) - local seasonal appearance

Based on 147 observations in Seymour township, Northumberland county, southeast Ontario, 1999-2004.

In this area the grackle returns at the same time as the robin and the blackbird, or soon after, and has been noted between 13 March and 26 September. It is however very uncommon after the third week of August.

The grackle is a common spring migrant, summer resident and early fall migrant at Presqu'ile provincial park, roughly 40 km to the south (LaForest, 1993, pp.374-375), as well as an uncommon migrant from early September to early November, and rare to occasional winter resident. Large numbers may be present in late August, prior to the main migration. The bird is also very common in Peterborough county, to the northwest, with the usual range listed as 02 March to 04 November (Sadler, 1983, p.158), although birds may overwinter.
