Off the topic, but I saw a crow in my yard today pick up a scrub jay
feather and continuosly call while holding it in its beak and repatedly
placing it on the ground to draw attention. The other crow near by paid no
attention, but I was fascinated by what the crow with the feather was
trying to convey. I know crows are very protective of their own, but why
would a crow display this kind of behavior over a scrub jay feather? Any
