A group of birds eagles and other birds have been hanging out on the Shoshone River, visible on the north side of the river bridge on Hwy. 310 between Lovell and Cowley.
According to baldeagleinfo.com, an eagle's body is protected by down under their feathers and their feet are resistant to cold, and mostly made of tendons. The beak is mostly non-living material with little blood supply. It seems these birds were better prepared for last night's -20 weather than I was.
The eagles were eating something on the frozen river. According to the site, eagles generally eat fish, but they will also eat other small prey and whatever else is available, sometimes scavenging for unattended carcasses.
