When to expect chimney swifts in Florida
Chimney Swifts are summer residents in Florida, arriving shortly before nesting begins in April and leaving after the young are independent. Through the season they feed on flies, beetles, ants and aphids in flight.
Humid subtropical in the north to tropical in the Keys; a wet summer and a dry winter season.
Nesting in Florida
Across Florida, chimney swifts typically nest from April–July. Nest site: half-cup of twigs glued with saliva inside chimneys. Females lay 4–5 eggs, incubate for 16–21 days, and young leave the nest after 28–30 days.
Heat, humidity and summer storms: boxes need drainage holes, ventilation and shade, and nectar spoils fast.
- Chimney Swifts don't use nest boxes. Keep dense native shrubs and trees such as southern live oak, flowering dogwood, serviceberry for nest sites.
- Delay heavy pruning of shrubs until after July.
