BNA is the definitive source of life history information for the more than 750 species of birds that breed in Canada and the United States (including Hawaii). Each species account is authored by an expert on that species and includes information on identification, distribution, behavior, breeding biology, habitat, food habits, migration, conservation and populations. Each species account includes multiple photos with identification tips, examples of sounds, and behavioral videos as well as a comprehensive bibliography of published research. As an online resource, BNA is continually updated.

Besides a new mobile device compatible page design, the new Birds of North America includes significantly more photos, videos and audio selections through the Macaulay Library (the world's largest and oldest scientific archive of biodiversity photos, videos and audio recordings). The new BNA now includes eBird data for more precise species distribution information and migration animations.
