Introducing the New Birds of North America
Birds of North America (BNA) is the most comprehensive reference for the life histories of over 760 bird species that breed in the United States and Canada. Species accounts are written by ornithologists and other experts and are an essential reference for anyone with an advanced interest in birds. BNA accounts have always offered an in-depth, authoritative summary of scientific literature and media. However, in combination with the Macaulay Library and eBird, our restructured species accounts are now accompanied by new sounds, images, and video, and distributional maps and model output generated by eBird.
Restructured Species Accounts
Species accounts have been redesigned and the site is now faster, with new functionalities, maps, and rich media. New tools will be added that will enhance user experience. Revisions of species account text are ongoing.
New Media from Macaulay Library
Integration with Macaulay Library means that a wealth of new audio, images, and video are now incorporated into species accounts, as are tools that allow users to search the full archive of Macaulay media resources.
Interactive Data Visualizations from eBird
Integration with eBird now provides interactive occurrence maps that are updated in real time and the most sophisticated models of bird distribution available.
