The northern cardinal is possibly a year-round resident, although
most sightings occur in a six-month period from late March to late
September. Extreme dates are 21 January and 28 October, with just
one sighting after 28 September.
It is a year-round breeding resident
at Presqu'ile provincial park, roughly
40 km to the south (LaForest, 1993, p.341).
It is apparently a relatively recent inhabitant, having first
been noted in Northumberland county in the late 1930s.
It is an uncommon year-round resident in southern
Peterborough county, to the northwest, and was first
reported nesting there in 1951 (Sadler, 1983, p.144).
