With Chimney Swift breading season here (May through July) it is a good idea to see if your chimney has a flue cover that will protect it from animal intrusion. The flue area of your fire burning systems, both furnace and fireplace, are sought-out by these birds that can fly in-and-out of vertical shafts.
The ideal nesting ground for Chimney Swifts would be hollowed out trees, but with the development of land and removed forestry allows insufficient nesting areas and they are forced to find a similar environment to nest. If you are hearing a chirping or chattering sound, coming from your fireplace, it could be the presence of Chimney Swifts.
By the way, Chimney Swifts are protected species and the protection of Chimney Swifts falls under the responsibility of the Migratory Bird Treaty Act (MBTA), and the U.S. Fish and Wildlife Service (USFWS), a branch of the Federal Government’s Department of the Interior is responsible for their protection.
Once a Chimney Swift has nested, the nest cannot be disturbed in any way until the eggs have hatched and the nest is no longer occupied.
Therefore, protecting your uncovered flue system could save you costly expenses and headaches.
