The following rules establish the standards and practices under which ALL World Series of Birding participants must comply. The rules are in fundamental accord with Big Day Count Rules established by the American Birding Association (ABA). Changes, where they occur, have been made to meet the needs imposed by team competition. Note that some categories of competition may have additional rules that govern participation.

All participants must be familiar with and comply with all rules, terms, and conditions (including those outlined in Exhibits A, B, C, and D below) in order to compete in the World Series of Birding. Failure in this regard may result in the disqualification of the team.
