Dust off those binoculars and brush up on your birding skills. The 2013 Great Backyard Bird Count is on and South Florida is a historical hotbed of action.

The four-day count -- a joint effort by the Cornell Lab of Ornithology, National Audubon Society, and Bird Studies Canada -- is a large-scale citizen-science project with participants from around the globe. There's no cost to join and it's open to birders of all levels, from the casual feeder watcher to hardcore "listers."
