When to expect blue jays in Wisconsin

Blue Jays live in Wisconsin all year. Cold, snowy winters; boreal finches visit the north. 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, with two Great Lakes shorelines, northern forest and southern prairie-oak savanna.

Nesting in Wisconsin

Across Wisconsin, 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.

Warm, humid summers.

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