From what I'm heard, Asheville's main spot for birdwatching is Beaver Lake Bird Sanctuary. A very neat place for birds and other creatures (including lots of ginormous frogs), and there were many of Asheville's resident birds there, including a little nuthatch! (Sadly no photo of the nuthatch though. Flighty little thing.)
This last one is a TERRIBLE photo, but this guy was so cool. A Northern Flicker.
