A robust bird code system: the six-letter code

This page is an older version of the author's writings on bird nomenclature systems. Please see the current version.

The system described here is designed for general use in the encoding of bird identities in field and other records anywhere in North America and Hawaii. It has been proven in several different projects, including a database of over three million records (see `The Christmas Bird Count database project').
