Red-eyed Cowbird 2 May 30 - about 6" from his tail to the F - flapping rapidly with puffed out neck and somewhat feathers thusly: Wings made a rustling noise. I believe he was looking directly at the F all the time. I could see no change in her stand or behavior. The tail of the OR was not fanned out to any degree. He hovered above the F for 5 seconds - "standing" in mid-air in the manner of a humming- bird. He then descended at the side of the F at once mounted and copulated for 3 seconds. The F then flew to top of cage and made several attempts to get around thru the wire, the OR flew up to a perch.
