American Birding Association

The American Birding Association (ABA) is a non-profit organization of people interested in birding. Membership is open to all, but many of its publications and programs have historically been aimed at birders who like making difficult field identifications and finding rare species. In more recent years, however, the ABA membership has drawn more broadly from the entire range of birders. The ABA supports competitive birding by, among other things, encouraging members to submit the numbers of species they've observed—in their lifetime,  in the current year, or in one day, for various regions—and publishing the numbers annually.
