When to expect American in Iowa
American Robins live in Iowa all year. Cold, windy winters; open farmland makes backyard shelter and feeders a lifeline. That makes the cold months the time your yard matters most to them: their winter diet shifts toward holly, juniper, sumac and crabapple fruit.
Humid continental prairie state, with loess hills in the west and the Driftless Area in the northeast.
Nesting in Iowa
Across Iowa, American typically nest from April–July. Nest site: mud-lined cup on a branch fork or ledge; uses open-front nest shelves. Females lay 3–5 eggs, incubate for 12–14 days, and young leave the nest after 13 days.
