The numbering system is based on the American Birding Association codes, but are for the status of that species in a specific county. Below I have pasted the ABA numbering system information that I copied off of the eBird site
.The American Birding Associations (ABA) birding codes were developed in 1982 and have been published with the more recent versions of the ABA Checklist. The most recent version of the ABA Checklist, the 7th edition, made a number of revisions to those codes. We use the ABA Codes to define what species are rare in the United States and Canada, which is useful for some of our data output. The ABA Codes are described on the ABA website and the definitions are reproduced here with permission. Please consider purchasing the 7th edition of the ABA Checklist for a more complete discussion of the ABA Birding Codes, as well as much information on rarities in the ABA area. Contact ABA Sales for more information. Code 1 and Code 2: Regularly occurring North American avifauna.
Includes regular breeding species and visitors. There is no firm designation between Code 1 and Code 2 species, except that logically Code 1 species are more widespread and are usually more numerous. Code 2 species have a restricted North American range, are more widespread, but occur in lower densities, or are quite secretive making their detection often difficult. We readily acknowledge that some Code 2 species are harder to find than some species that have higher codes.

Code 3: Rare.
Species that occur in very low numbers, but annually, in the ABA Checklist Area. This includes visitors and rare breeding residents.

Code 4: Casual.
Species not recorded annually in the ABA Checklist Area, but with six or more total records—including three or more in the past 30 years—reflecting some pattern of occurrence.

Code 5: Accidental.
Species that are recorded five or fewer times in the ABA Checklist Area, or fewer than three records in the past 30 years.

Hi Christine,&#65533;Sorry about that - code 5 is rare.&#65533; I use the codes that are on the Washington Birder website (
http://www.wabirder.com/county_map.html).&#65533; The codes appear next to the listed species on the county checklists.&#65533;Jim--

Would someone list what the different codes mean? &#65533;I gather that a "Code 5" is rare. &#65533;And which listing references these codes?

I'm sure I'm not the only one who doesn't know.

Thanks,
