Great Backyard Bird Count
16th Annual Great Backyard Bird Count - February 15-18, 2013
You're invited to be part of a massive citizen-science effort across North America. Tens of thousands of fellow bird watchers will be counting birds and submitting their checklists to www.birdcount.org. Just watch birds for at least 15 minutes at any location and tally the highest number of each bird species you see at any one time. Submit a new checklist for each day and each new location where you count.
