Postfledging Dependence Period of Migratory Golden Eagles (Aquila Chrysaetos) in Denali National Park and Preserve, Alaska
Abstract The postfledging dependence period is not well documented for many species of raptors, including Golden Eagles (Aquila chrysaetos). From 1997 to 1999, we used satellite telemetry to estimate the length of the postfledging dependence period, and the finite survival rate of fledglings during...
