Sara - Most birders follow the protocols set by the American Birding Association (ABA), which lists ABA-area countable birds, as well as the ease/difficulty of seeing the bird in the appropriate area. Number "1" is an easy bird to find, while Number "6" is considered likely to be extinct. Though this list is sometimes referred to as a "North America" list, it excludes Hawaii and Mexico, which is geographically part of North America.
From ABA: "The ABA Checklist includes ABA-area breeding species, regular visitors, and casual and accidental species from other regions that are believed to have strayed here without direct human aid, and well-established introduced species that are now part of our avifauna. Species Total: 981"
To download the most current ABA checklist, go to:
listing.aba.org/aba-checklist/
Some of the exotic or introduced birds are considered countable only from specific locations, such as Nanday Parakeet, Nutmeg Mannakin and Rosy-faced Lovebird, among others.
However, a birder's list is a personal endeavor so you may count any bird that you wish to add to your list. Birders who submit their lists to ABA adhere to the ABA protocols. I hope this helps. Perhaps others will add their thoughts.
