Important Bird Areas

Port Bolivar Bird Sanctuaries - Bolivar Flats

At first glance, you might not see the special qualities of Bolivar Flats, a unique area combining salt marsh, mud flats and beach, each habitat quite different from the other. Every year hundreds of thousands of birds discover that Bolivar Flats is a special place. Here they find a resting place and nesting habitat where a smorgasbord of invertebrates and fish is spread. Decomposing plant material derived from the salt marsh and delivered by the coastal currents feeds millions of small worms, shrimp and clams which live in the mud flats. Thousands of birds, small fish and crabs hunt the shallows for these invertebrates and small fish that venture into deeper water.
