If you cannot wait until the babies have fledged you may contact a licensed wildlife cooperator to help you find a solution. Chimney swifts are protected by the Migratory Bird Treaty Act and a federal permit is needed to remove birds and their nests during the nesting season.
The chimney swift looks very much like the closely related Vaux's swift, but is slightly larger, with relatively longer wings and tail, slower wingbeats and a greater tendency to soar. It tends to be darker on the breast and rump than the Vaux's swift, though there is some overlap in plumage coloring.
