Get ready to count!
Here's a description of this event from the Audobon Society's website at http://www.audubon.org/gbbc/
"The 13th annual Great Backyard Bird Count (GBBC) will be held from February 12 – 15th, 2010. The GBBC is an annual four-day event that engages bird watchers of all ages in counting birds to create a real-time snapshot of where the birds are across the continent and in Hawaii.
Each checklist submitted by these "citizen scientists" helps researchers at the Cornell Lab of Ornithology and the National Audubon Society learn more about how the birds are doing—and how to protect them and the environment we share. Last year, participants turned in more than 93,600 checklists online, creating the continent's largest instantaneous snapshot of bird populations ever recorded.
Anyone can take part in the Great Backyard Bird Count, from novice bird watchers to experts. Participants count birds for as little as 15 minutes (or as long as they wish) on one or more days of the event and report their sightings online at www.birdcount.org."
