Bald eagle population on the rise: Sightings on East End becoming more common

The bald eagle population is soaring once again thanks to a ban on mosquito pesticide Dichlorodiphenyltrichloroethane (DDT), and a concerted effort by the New York Department of Conservation. Fifteen breeding pairs were monitored by the DEC last year. Although eagles typically return to the same nest each season, they will often build one or two alternate nests within their breeding territory.

Bald eagles belong to a sub-family of eagles known as sea eagles. The bald eagle is the only sea eagle that takes up residence in North America. They are endemic to North America (meaning they are found nowhere else), with a range from Alaska and northern Canada, south to Mexico.

They prefer to live adjacent to large bodies of water, such as lakes, rivers, bays, and the ocean. With a life along the water, bald eagles primarily feed on fish, and at 3-feet-tall with a wingspan greater than 6 feet, they are capable of preying on quite large fish.

Not only do bald eagles need to live in close proximity to large bodies of water, but they also require trees that are large enough to support a nest that can be 4-to-5 feet in diameter and 2-to-4 feet deep.

With 15 known nesting pairs monitored by the Department of Environmental Conservation and an influx of migratory juveniles, during the winter months, you no longer need luck to see a bald eagle on the East End.

Unlike the movies, a bald eagle’s call is a series of high-pitched chirps. The eagle call in a movie is actually that of a red-tailed hawk. Some East End spots to observe bald eagles are the Riverwalk in downtown Riverhead, Indian Island County Park, and the many farm and sod fields along Sound Ave and County Road 48.

“Skyway” robbery, where an eagle steals an osprey meal mid-flight, is a common occurrence. Another shocking trait of the bald eagle is they often feed on carrion, which is the decaying flesh of dead animals. This “dirty” trait also makes them frequent visitors at the local dump.
