The database supports data from published atlases and also serves as a management tool for implementing these large-scale surveys. The shared data management system has allowed for cost-effective project implementation for agencies in many states. Currently the database houses 35 published and ongoing atlas projects. Data and maps from BBA Explorer have also been used in the preparation of breeding bird atlas books.

A Breeding Bird Atlas (BBA) is a population survey project designed to cover large geographic areas using a grid based system and is generally organized at the state or provincial level. Each participant in the project, referred to as an observer or 'atlaser', is assigned one or more blocks (grid cells) in which to conduct extensive area searches. They record any breeding evidence observed for each bird species; this evidence is categorized as “confirmed”, “probable” or “possible”. The results can be mapped and will then provide comprehensive information about the distribution of breeding birds in the region covered. For more information on BBAs see the North American Ornithological Atlas Committee (NORAC) website. unkown Mark Wimer Patuxent Wildlife Research Center Acting Director
