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.
DON'T remove active nests of any native bird, including Tree Swallow, Tufted Titmouse, or chickadee nests. It is illegal to disturb an active nest of any bird except House Sparrows, starlings and pigeons, which are not protected.
