Didn't have to leave the house today to see a good bird.  Happened to be looking thru the back patio door when a group of corvids approached.  Seeing crows fly by isn't unusual but immediately noticed that the lead bird was using a flap-flap-glide flying style while the other crows (5) were using continuous wingbeats.  As they passed by the house saw that the lead bird was slightly larger than the others and that the second bird was trying to pull at the tail feathers of first bird.  By the time I got outside they soon disappeared behind a neighbors house, and the crows were last seen chasing the raven flying northward, in the general direction of I-70.
