Today's report includes a final migration map for each satellite-tracked eagle, along with 3 season's migration data for 2 western eagles.
Satellite tracking gives biologists a sample.
But the migrations of individual birds actually represent the movements of a whole population. In the west, Jim Watson reminds us that each satellite-tracked eagle really represents a thousand or two migrants. Based on Watson's observations of other breeders, they should depart within 3 or 4 days in consecutive years. Biologist Nye summarizes the whereabouts of each eagle, then asks you to consider the questions that are running through his own mind right now . This unscheduled report brings news about some exciting developments in Peter Nye's study.
