The Ruffner Mountain Nature Center will host the Christmas Bird Count bird watching hike on Saturday, December 21 from 8:30 a.m. to 12:30 p.m.! Winter is a perfect time to see birds because of the lack of foliage on the trees. This hike is open to all levels of birders, from beginners to experienced, and all levels in between. Not only will we identify birds by sight, but we will also learn the common calls of several birds. Moderate hike.
