Have been watching a Sharpie out in the yard for about 15 minutes now. It and the crows keep getting in minor dust-ups - it seems to be trying to chase the crows out of the yard - landing on the ground near them, then making runs at them. I'm guessing it's pretty hungry - also saw it go after a mature squirrel that probably outweighs it.

Needless to say, the finches have all made themselves scarce!
