Pam Randles, Takshanuk Watershed Council Education Director, records the measurements of a bald eagle captured in the Alaska Chilkat Bald Eagle Preserve by researchers studying bald eagle migration. Rachel Wheat a graduate student at the University of California Santa Cruz is conducting a bald eagle migration study of eagles that visit the Chilkat River near Haines, Alaska for her doctoral dissertation. She hopes to learn how closely eagles track salmon availability across time and space. Wheat is tracking bald eagles 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. 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.
