Proudly American
Leave the opening and birds undisturbed
Do not light a small fire to encourage birds to leave, send a brush down the flue, or have a cap fitted over the opening while birds may be inside. The US Fish and Wildlife Service describes chimney swifts as protected migratory birds and advises planning cleaning outside nesting and roosting periods. Other species or an injured animal can require a different response.
Gather observations from a safe distance
Note the dates, the times you hear activity, and whether birds were seen entering or leaving at dusk. Watch from the ground. Leave eggs, nests and young birds in place. If a bird is in the room or appears injured, keep children and pets back and seek instructions from a local wildlife rehabilitator or wildlife authority.
Coordinate the next fireplace appointment
Ask for wildlife guidance on when the chimney is clear before rescheduling a sweep or changing the top. One quiet afternoon does not establish that a nest is empty. Once access is appropriate, discuss a chimney inspection before returning the fireplace to use and whether any exclusion or conservation option suits this particular working chimney.
