When to expect Carolina wrens in Missouri
Carolina Wrens live in Missouri all year. Cold winters with variable snow; ice storms can shut down natural food for days. That makes the cold months the time your yard matters most to them: their winter diet shifts toward suet, peanut pieces and mealworms at feeders.
Humid continental, from the Ozark Plateau in the south to prairie and river floodplains in the north.
Nesting in Missouri
Across Missouri, Carolina wrens typically nest from April–August. Nest site: domed cup in any cavity — hanging planters, sheds, mailboxes, brush. Females lay 3–7 eggs, incubate for 12–16 days, and young leave the nest after 10–16 days.

- Have boxes cleaned and mounted before March — Carolina wrens begin prospecting ahead of egg-laying.
