When to expect chimney swifts in Nova Scotia

Chimney Swifts are summer residents in Nova Scotia, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on flies, beetles, ants and aphids in flight.

Maritime — cool summers, snowy but ocean-moderated winters, fog and wind along the coast.

Nesting in Nova Scotia

Across Nova Scotia, chimney swifts typically nest from June–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.
