Blue jays are much better fliers and will steal peanuts away from crows who will sit watching stupefied and hopeless and hope for a second peanut. It seems that the blue jay color-scheme is blind to crows.

A long time ago (when I was a teenager), I did maim a crow with a miracle long-distance Crossman shot (across the street, on top of a large tree.)

Before that, I had shot at crows at much-closer distances to no effect.

This time, the crow tumbled out of the tree and skipped about.

I went across the street to look at it closer, and realized it was bleeding out of a wing joint and could no longer fly.

I chased it about a bit, and delivered a kill shot to it's brain.

I soon realized that 50 crows were swarming about above me yelling in anguish. I got the hell out of there and was guilt-ridden.

Thus, from that point on, I no longer use the Crossman to kill, and to respect crows ala Native Americans. I now feed them on my way back and to the bus stop.

I've been doing this penance for three years in my neighborhood and now have crows flying to me from blocks away to get their peanuts.

The interesting thing is, over this three-year period, how do the crows recognize me? I've gone from clean-shaved to bearded, sometimes I carry a sportsbag, sometimes I don't, sometimes I'm dressed for work, sometimes casual, I usually walk about at the same times, but sometimes don't, hell, sometimes I exit/enter a different bus stop, sometimes I merely take out the garbage at a random time...

...in all cases, the neighborhood crows will often recognize me and fly close for a tasty peanut...

Wait; what was I talking about?
