If you're involved with Christmas or Breeding Bird Counts, the boundaries of your count circle are always of interest, and sometimes unclear. Count Circle includes the complete National Audubon database of CBCs, with a total of 2883 different count circles in 93 different states and territories including Canada, Mexico, the Caribbean, South America, and Antarctica (updated as of December 2018). Lookup and display any count circle on an interactive map, and find out exactly what is (and is not) included in the circle. The software also displays your current location, so you can determine precisely if you are inside or outside the count circle as you are doing your count.
You can also use Count Circle just to view the different circles, to help you decide which ones you might like to participate in. Display all the circles in your state with one click.
If you have reason to believe the database is in error, Count Circle lets you set the center of the circle, then update the database, and even, if you choose to do so, report the revision directly to National Audubon, who then review the update.
You can also create and save your own circles, and, combined with the ability to display multiple existing circles, this provides the perfect way to position a potential new circle so that it doesn't overlap existing circles. You can even choose the radius (in miles or kilometers) if you want to use something other than the "standard" 7.5 mile radius used for the CBC. A great addition for "patch challenges"!
Note: some reviewers have noted errors in the count circle locations. The data in the app is the latest data direct from the National Audubon Society. Any errors in location stem from that database, NOT from the app! This is precisely why the app includes a feature that lets you report such errors directly to Audubon, so that Audubon can correct such errors in future updates of their database.
