Mini Bird Breeding Survey

A Mini Breeding Bird Survey (MBBS) is a small-scale version of the full Breeding Bird Survey organized each year by the U.S. Fish and Wildlife Service throughout North America. An MBBS focuses on one county. Volunteers count birds seen or heard along randomly chosen routes on secondary roads. The objective is to determine the distribution of breeding birds in the county and to assess any year-to-year changes in their numbers.
