The forest, shrublands, and beaches of the Norwalk Islands are recognized as regionally significant habitats for colonial nesting birds like herons and egrets, vital nesting and migratory habitat for neotropical birds, and high-quality wintering grounds for waterfowl.

Sheffield Island’s nature trail and sandy beach offer visitors an excellent vantage point to observe and photograph water birds, beach life, and other nature scenes. Guided tours of the nature trail, beach, and the historic Sheffield Lighthouse are often available during summer.
