The robin is a very common spring migrant
(early March to early May) and a common fall
migrant (early September to mid-November)
at Presqu'ile provincial park, roughly
40 km to the south (LaForest, 1993, pp.283-285).
A few sightings have beem made in December, January, and February
(with a possible "earliest returnee" on 22 February 1976).
It nests throughout the park.
The bird is also very common in
Peterborough county, to the northwest,
with the usual range listed as 02 March to 03 November
(Sadler, 1983, pp.123-124), although birds may stay
later if the berry supply is good. The earliest returning bird may
have been on 29 January 1983, "in that phenomenally mild winter".
