Yesterday, once again, both Ellie and Eddy spent a good chunk of time in or around the nest keeping an eye on the roofers.
I enjoyed watching Ellie spend a considerable amount of time preening.
Preening involves the application of a waxy, fatty secretion from the preen gland that is located at the base of the tail. Feathers would become brittle from age and weather exposure without the regular application of this oily substance. This action cleans the feathers and preserves their moistness and flexibility, and provides waterproofing necessary to withstand a life that is lived entirely in the out-of-doors.
“An eagle can rotate its head approximately 180 degrees in each direction. Eagles have 14 cervical vertebrae allowing for greater rotation than humans who have just 7 cervical vertebrae and can typically rotate just 70-90 degrees in either direction.”
