Oh great, thanks, give me another to worry about :-)
I've never seen a weasel round here... but I guess that doesn't mean it couldn't be... it was weird that dead chickens (probably 6 or so) were drug all over the yard, but not eaten... I figured I interrupted him in the process, but still doesn't answer why he wouldn't have just grabbed one and eaten it... kept going back in and getting others... but the hole that was dug was quite a bit bigger than a weasel would have probably dug (I could probably have fit a basketball thru the hole).

I've attached a couple pictures of red-tailed hawks that my brother took... their head, face, and eyes look nothing like mine... that's why I've been so confused.

Does anyone know if there is much of a difference between male and female? Of is it all just an age thing? But these my brother took (with an obvious red tail) look nothing like the last picture I posted that was identified as a red tailed...
