This evening I ran out to Market Lake Wildlife Management Area to see if I could find the Great-horned owls that usually nest there. They were easy to find as the magpies were attacking them. The pair were roosting on the same limb, but the male quickly attack only to pull up short, but came within a couple of feet of me. He was not a happy camper.
Here is the male after the attack. He would try to ignore me and then would fly away.-h
Here is the smaller female. She never flew but watched me very closely.
Here she is as the sun was setting.
Here is a Rough-legged hawk that kept buzzing the male Great-horned owl.
