Birds of the World is a research database that brings together scholarly content from four major works of ornithology [Birds of North America, The Handbook of Birds of the World, Neotropical Birds, and Bird Families of the World], millions of bird observations from eBird, and multimedia content from the Macaulay Library into a single platform where biologists and birders can explore comprehensive life history information on birds. Birds of the World presents a vast array of information about every species, subspecies, and family of the world's birds. Accounts include images, sounds, and videos as well as illustrations, maps, animations, and authoritative text from all of the component projects

Bird Species of Special Concern (BSSC) Implementation website, a collaboration between PRBO Conservation Science and the California Department of Fish and Game, aims to implement the recommendations detailed in the 2008 BSSC monograph in order to prevent further declines of California's native birds. In addition to the 2008 BSSC report, this site provides access to maps, climate data, and related literature.
