Thanks for the link. I observed a flock of "mourning" crows around a dead one in the field behind my yard. I was flabbergasted at what I was seeing.
So they are mourning and investigating the cause of death for the sake of the flock. Wow!
Thanks for linking this, I had been wondering what the heck I had observed. It was really interesting. I love watching them. I almost always see something new (for me)
