Why is Birds of the World a subscription service?

By lacing together content from four publications, two multimedia libraries, and a dataset of 700 million bird observations, Birds of the World was a monumental undertaking. Going forward, developing and maintaining comprehensive ornithological life histories for all bird species and families requires not only the appropriate digital publications infrastructure to house this work, but it also involves engaging a global team of editors and writers to ensure the content is up-to-date and authoritative.

Birds of the World generates project revenue by charging individual and institutional subscribers access fees. Every dollar generated by these paid subscriptions goes back toward supporting the technical development and content generation aspects of the project. This revenue also allows us to make Birds of the World freely available to thousands of people around the world, with a special focus on providing access in areas where students, researchers, and conservationists critically need the information we’re providing. Our goal is to generate enough revenue to support the growth and development of Birds of the World, while making its services available to the broadest possible array of audiences.
