Marine life of New York–New Jersey Harbor Estuary

Many of these birds will fly within sight of the Manhattan skyline and the estuary is a very important point for the East Coast because of its location: it is dead center in the Atlantic Flyway and many raptors and waterfowl use this spot as a rest area along their journey from New England and Canada in fall before heading further south to the Southern States and the Caribbean, reversing the journey in late March and early April.

[9] They were once fairly common to the estuary, as evidenced by records left behind by the Dutch describing them in a way that is unmistakable for any other family of fish, and cousins of sharks like the skates and rays never totally went extinct in the waters off New York or New Jersey.

From 2007-2009, an expert from Cornell University did an experiment listening in on the acoustics of the Harbor Estuary, where, to the astonishment of many, he discovered at least six species of whale vocalizing less than 20 miles from where the Statue of Liberty stands, just past the Verrazano Bridge where the water gets deeper.

In 2009, however, a young humpback whale attempted to penetrate the gateway to the upper harbor when it passed under the Verrazano Bridge, causing the men and women ashore watching the whole debacle from Fort Hamilton a great deal of alarm, concerned for its health and the safety of the Coast Guard officers trying to herd the frightened, massive creature back out to sea (the whale returned unharmed.
