Rachel Wheat, a graduate student at the University of California Santa Cruz attaches a U.S. Geological Survey (USGS) leg band to one of the bald eagles in her bald eagle migration study. The bald eagles in her study receive two different leg bands. Along with the silver aluminum USGS leg band, eagles also receive a bright green auxiliary leg band. The bright green leg bands have larger identification information than the USGS bands making it more easily read using a spotting scope. 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. Wheat is tracking bald eagles using solar-powered GPS satellite transmitters (also known as PTT - platform transmitter terminal) that attach to the backs of the eagles using a lightweight harness. Should the GPS transmitter fail or if the bird is found dead, spotted or recaptured, the leg bands can be another source of information. The latest location of this bald eagle known as "2Z" can be found here: http://www.ecologyalaska.com/eagle-tracker/2z/ . 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.
