All that food for them and no gifts? What gives?

Loved this documentary from the other thread:

I've never noticed any gifts, but I haven't looked either. I think I'll have a look at the area where we feed them. Maybe I'll find someone's lost diamond ring or something.

There's plenty of crows around here and there's some scraps we can set out for them.

We are, by far, the most destructive, which probably counts against us if there's any objective measure of "intelligence."

I'm pretty sure the crows and ravens are much more aware of what goes on in our neighborhood than any of us humans.

If space aliens or gods drop by and want to know what's happening they probably ask the crows first.
