North American Breeding Bird Survey Home

Welcome to the North American Breeding Bird Survey (BBS) web site. The BBS is a cooperative effort between the U.S. Geological Survey's Eastern Ecological Science Center and Environment Canada's Canadian Wildlife Service to monitor the status and trends of North American bird populations. Following a rigorous protocol, BBS data are collected by thousands of dedicated participants along thousands of randomly established roadside routes throughout the continent. Professional BBS coordinators and data managers work closely with researchers and statisticians to compile and deliver these population data and population trend analyses on more than 400 bird species, for use by conservation managers, scientists, and the general public.
