Crows Can Recognize The Calls Of Relatives
Jessica Yorzinski '05 [Cornell] found seven subtle acoustic differences in features that differed among individuals -- differences that the crows could potentially use to recognize one another's calls. She also found that female crows had higher-pitched calls than males.
Okay, so it doesn’t say it is so, but the study does show there is a potential there that needs to be explored.

I once read that crows are the only birds that fly for the fun of it sometimes. They do have a sense of humor, though. There is an old building on the property next to ours that was renovated a few years ago as a hardware and landscaping supply store. It's about sixty or seventy feet long and has large, industrial size rain gutters running across the eaves. The crows all gather on the roof and take turns running the length of the gutter, their claws clicking and clacking all the way. I've sat and watched them do this for almost an hour before they got tired of it and flew away to do who knows what.
I guess crows have talons, don't they.
I am not a bird watcher but I am a retired gardner and grew both field and sweet corn when I was gardening. Oddly enoughI like to watch all manner of creatures in their natural habitat, they're fascinating and marvelous.
Crows are especially interesting but when they become destructive the whole scenario is altered when it concerns myself and the family. One day about a dozen or more crows were happily tearing out my young corn sprouts, I killed two and wounded one with my 12 Ga. shot gun. The wounded crow lay in the garden squawking and soon the sky above was darkened with crows from miles around calling to their wounded companion. After the wounded crow died the crows gradually flew away and for quite sometime they did not return to the area so crows do communicate even when dying. I'm sure the wounded crow was telling it's associates to stay the heck away from this area.
