The thin black birds seen in flocks on Lake Tallavana are Cormorants. These birds are Federally protected under the Migratory Bird Treaty Act.https://www.fws.gov/southeast/faq/double-crested-cormorants/ Currently they may not be shot, shot at or harmed in any way unless a special permit has been issued. U.S. Fish and Wildlife is not currently issuing permits for removal. Tallavana Homeowners' Association does not have a permit to shoot Cormorants.
The recommended way to discourage them inhabiting our lake is to remove nests after any eggs have hatched as eggs are protect as well. Place bird spikes on docks or in trees, use motion activated lawn decor. Ideally, scaring the scout that comes in the early spring is the best way to ensure the Cormorants not invade our lake.
