Tidal Bays and Marshes

Saltwater wetlands are very productive habitats for birds. They act as nesting sites for dozens of species of breeding birds, and are important staging areas for migrating landbirds. In winter, huge flocks of waterfowl that breed in the arctic call New York’s tidal bays and marshes home. Tidal bays and marshes are among our most vulnerable wildlife habitats, because they occur in the most densely populated parts of the state.

Sea Birds and Salt Water

Too much salt in your diet? Seabirds ingest a lot of saltwater every day. How do their bodies deal with so much salt? They have evolved a pair of glands (that sit between their eyes) that extract salt from their blood and enable them to excrete the excess salt through their nostrils.

Larus argentatus 

Notice the depressions above the eye sockets where nasal glands were located.

Thirty-six of Audubon New York’s Important Bird Areas are found in tidal bays, marshes and estuaries.

The Hudson River Estuary is a mix of fresh and salty waters. It experiences daily tides all the way to the first barrier on the river channel—the Federal Dam at Troy, some 154 miles upriver from New York City.
