A bald eagle (Haliaeetus leucocephalus) flies away with the head of a chum salmon (Oncorhynchus keta) carcass over the Chilkat River in the Alaska Chilkat Bald Eagle Preserve near Haines, Alaska. 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. The preserve is located downstream of where Constantine Metal Resources, Ltd. is exploring an area known as the Palmer Deposit as a location for a hardrock mine. (John L. Dengler)
