American Goldfinchs in Michigan

American Goldfinchs live in Michigan all year. Lake-effect snow and long cold spells; Purple Finches breed in the north and winter farther south. That makes the cold months the time your yard matters most to them: their winter diet shifts toward birch and alder seeds; nyjer and hulled sunflower at feeders.

Humid continental, strongly shaped by the Great Lakes; colder and snowier in the Upper Peninsula.

Across Michigan, goldfinches typically nest from July–September. Nest site: tight cup in shrubs or saplings, lined with thistle or cattail down; nests late, in July–September. Females lay 2–7 eggs, incubate for 12–14 days, and young leave the nest after 11–17 days.

A compressed nesting season; bluebirds usually manage one or two broods.

• American Goldfinchs don't use nest boxes. Keep dense native shrubs and trees such as paper birch for nest sites.
• Delay heavy pruning of shrubs until after September.
