Black-bellied whistling ducks (Dendrocygna autumnalis) normally hang out in the southern states, Florida, Texas, Louisiana, etc. But on June 12, 2019, I visited Nickerson Beach on Long Island and saw a small flock of them chewing up the lawn between the parking lot and Lido Boulevard. These ducks are very sociable, and what I noticed watching them was that as most of them were lawn-mowing with their heads down chomping away, one would almost always be upright, checking out the neighborhood for danger.
The Filming the Feathers video shows the black-bellied whistling-ducks forage on the lawn at Nickerson Beach, and then flying off when one of the ducks thought it time. The music is by Johann Sebastian Bach.
All of the photos below were taken on June 12, 2019, at Nickerson Beach.
