The Great Backyard Bird Count is one birding activity that can be done from literally anywhere on the planet. Join hundreds of thousands of people of all ages and walks of life to create a snapshot of birds across the world. All you have to do is spend 15 minutes tallying the numbers and types of birds you see on one or more of the days of the count. You can count birds at your local park, nearby wildlife reserve, or your own backyard. To find out more and sign up, check out the link below.
