The North American Breeding Bird Survey is a cooperative effort between the United States and Canada.
The bird survey is a long-term, large-scale, international avian monitoring program started in 1966 to track the status and trends of North America's birds. If significant declines are detected, causes can then be identified and action taken, to reverse them before populations reach critically low levels.
This episode of Playa Country is the second in a five-part series on citizen science and the role it plays in the understanding of birds. This program first aired on HPPR 6/17/14.
