Cadillac Square and its complement of old Live Oaks is a star attraction on Dauphin Island. Migrant warblers and other songbirds may be observed up close and personal. Black-whiskered Vireo has been a visitor in the recent past. The Live Oaks throughout this historic site are all that remain of the home of Governor Cadillac and the capital of the Louisiana Territory.
This is a simple preform tube hidden in a bush behind the migratory bird sign, you can see the sign near the restrooms in the picture posted below
