When to expect blue jays in Ontario

Blue Jays live in Ontario all year. 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 acorns and beechnuts, heavily cached in fall; peanuts, sunflower and suet 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, blue jays typically nest from May–July. Nest site: open cup of twigs in tree crotches, usually 10–25 ft up. Females lay 2–7 eggs, incubate for 16–18 days, and young leave the nest after 17–21 days.

Short, warm summers; Point Pelee and Long Point are continent-famous migration sites.

Blue Jays don't use nest boxes. Keep dense native shrubs and trees such as oaks, white oak, bur oak for nest sites.
Delay heavy pruning of shrubs until after July.
