The U-shaped island in the middle of Clay Bottom Pond has become a favored roosting and nesting place for thousands of waterbirds. In the spring and summer, herons, egrets, cormorants and spoonbills build their nests and raise their chicks on the predator-free island. Visitors to the sanctuary are able to get a good close look at the home life of these beautiful birds throughout the breeding season.
Year round the island is used as a night roost by the same species of birds that nest here. The appreciate having a safe place to spend the night that is close to the marshes where they feed. The most spectacular time of day to visit the rookery is the last hour before dark when the birds are coming in for the night.
