Steve Lewis, Raptor Management Coordinator, U.S. Fish & Wildlife Service, places camouflage on a net launcher that he is using to capture bald eagles on the gravel bar of the Chilkat River. The net launcher, along with leg snare traps, is being used to capture bald eagles that will be used in a study being conducted by Rachel Wheat, a graduate student at the University of California Santa Cruz. Wheat is conducting a bald eagle migration study of eagles that visit the Chilkat River for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. The bald eagles are being tracked using solar-powered GPS satellite transmitters (also known as a PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. Pictured in the background is the Tlingit village of Klukwan. During late fall, bald eagles congregate along the Chilkat River to feed on salmon. This gathering of bald eagles in the Alaska Chilkat Bald Eagle Preserve is believed to be one of the largest gatherings of bald eagles in the world.
