Peter Nye


Peter Nye, retired from New York’s Department of Environmental Conservation, is one of the top eagle biologists in the nation. He was a pioneer in re-establishing eagles after their population declined dramatically, due to DDT.

He is credited for bringing back the Bald Eagle to New York state.

In 1976, Peter developed a way of raising young eagles known as hacking. Nye and his colleagues went to Alaska, where eagles were still abundant, and gathered young. Like foster parents, they raised the young eagles back in New York in hacking towers until the eagles were old enough to fly. Slowly but surely, year after year, the population has continued to build. In fact, there were 70 nesting pairs that fledged 94 young Bald Eagles in New York in the summer of 2002!

Nye is also a pioneer in the high-tech migration-tracking method called satellite telemetry.
