The Great Backyard Bird Count, that is.
It's fun, family-oriented and it's for a great cause as well. The count lasts four days and starts today, on the 15th. The last day to participate is on Monday. All you have to do is count the birds that you see and report it on this website.
The GBBC Website in association with BirdSource.org
The information gathered will be used in projects and programs to help protect and save birds around the world. This year, GBBC goes global so if you are in South America, the Yukon Territories, or in downtown Sydney, Australia, you can count birds and make your record count!
I've already uploaded my first checklist for today.
