"The Great Backyard Bird Count 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. Anyone can participate, from beginning bird watchers to experts. It takes as little as 15 minutes. " GBBC is a joint project of the Cornell Lab of Ornithology and National Audubon Society.
January 2007 was the warmest on record, did that impact the distribution of birds in 2008?
