Birds of North America (BNA) is a comprehensive reference for the life histories of 760 bird species that breed in the United States and Canada. Once a print serial monograph, it is now a subscription-based online digital resource maintained by the Cornell Lab of Ornithology in collaboration with the American Ornithological Society.
BNA is highly regarded by ornithologists, professors, teachers, and professional biologists as the most authoritative scientific resource on North American birds and is available in hundreds of public and academic libraries as well as in government agencies, consulting firms, nature centers, and nonprofits across more than a dozen countries.
BNA's extensively referenced species accounts are written and continually updated by ornithologists — thus making it an essential tool for anyone with an advanced interest in birds.
The Cornell Lab offers flexible pricing and access arrangements that allow all or designated members of an institution complete access to BNA species accounts. Pricing depends upon the type and size of the institution/organization, the nature of use, and the number of potential users. Access is typically granted by IP address ranges and remote, off-site access can be arranged.
