About the Bald Eagle Migration Study

For the 15th season in a row, New York biologist Peter Nye will share satellite telemetry data with students as he tracks the travels of adult Bald eagles in New York state.

Satelite tracking data from adult eagle PTT's will provide students with a great opportunity to compare and contrast the migrations of individual adult eagles. Students can review previous migration data, learn about eagle habitat and diet. They can also explore Canada's climate, and how weather systems affect each eagle's journey using real-time weather data. With all this information, students then estimate when the eagles will head back north to their individual nesting sites.

Biologist Peter Nye and Bald Eagle with Satellite Transmitter (PTT)
As a refresher, here are the 4 bald eagles that we are still tracking; all are adults and all were captured along the Upper Delaware River of New York:

U21 = female, captured 15 January 2006; ptt#59786
U25 = female, captured 25 January 2006; ptt#59787
U27 = female, captured 1 February 2006; ptt#59788
S28 = female captured 7 January 2008; ptt#59794

Nye believes the timing of an eagle's departure from New York is a clue to its ultimate nesting destination. The further north the eagle's nest, he theorizes, the later it leaves New York. This suggests the eagle has an incredible sense of timing. Study all our migration maps to answer this: Which eagles do you suppose will migrate latest?

Background

Recently removed from the endangered species list, the eagle's recovery is a conservation success story. Students will learn about DDT in the food chain and analyze eagle population statistics during the years of its recovery. New research, however, suggests other chemicals in the environment may now be threatening eagles. Nye's work in New York is presently measuring levels of such chemicals. Thus, while conservation challenges continue to confront eagles, past lessons have made scientists and citizens more watchful.
