Bird Conservation Regions

Learn About Bird Conservation Regions

Birds do not abide by political boundaries. The divisions between states and countries mean less to birds than the differences between habitats, landscapes and resources. To that end NABCI has redrawn the map of North America as it applies to coordinated bird conservation needs.

What is a Bird Conservation Region (BCR)?

BCRs are regions that encompass landscapes having similar bird communities, habitats, and resource issues. They are the fundamental biological units through which NABCI will deliver landscape-scale bird conservation, including evaluation, planning, and in many instances, implementation. 67 Bird Conservation Regions have been identified, 35 entirely or partially in the United States, 3 strictly in Canada and 29 strictly in Mexico.
