Dr. Chris Wilmers, associate professor, University of California Santa Cruz, holds a blood sample taken from a bald eagle (Haliaeetus leucocephalus) captured in the Alaska Chilkat Bald Eagle Preserve. Wilmers was assisting, Rachel Wheat, graduate student at the University of California Santa Cruz in the processing of eagles she is studying. Blood samples are taken of the eagles to study for various things including chemical contaminants such as mercury. 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. 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.
