When to expect cardinals in Ontario
Northern Cardinals live in Ontario all year — southern Ontario; range still expanding north. Cold, snowy winters; feeder flocks are dominated by chickadees, nuthatches, woodpeckers and finches. That makes the cold months the time your yard matters most to them: their winter diet shifts toward weed and grass seeds; sumac, hackberry and other persistent winter fruit; sunflower and safflower at feeders.
Humid continental in the south, boreal and subarctic in the north; most backyard birding happens in the southern Great Lakes lowlands.
Nesting in Ontario
Across Ontario, cardinals typically nest from May–August. Nest site: open cup built by the female in dense shrubs, vine tangles or saplings, usually 1–15 ft up. Females lay 2–5 eggs, incubate for 11–13 days, and young leave the nest after 7–13 days.
Short, warm summers; Point Pelee and Long Point are continent-famous migration sites.
- Northern Cardinals don't use nest boxes. Keep dense native shrubs and trees such as serviceberry, red-osier dogwood, nannyberry for nest sites.
- Delay heavy pruning of shrubs until after August.
