Mini Breeding Bird SurveysOrange, Chatham, and Durham CountiesNorth Carolina
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.
An annual MBBS began in Orange County (12 routes) in 1999, in Chatham
County (14 routes) in 2000, and in Durham County (8 routes) in 2002.
The number of routes in each county varies with the size of the
county.
The first decade of MBBS (1999-2009)
2009 was the
eleventh consecutive year for Orange County,
During this period we covered all routes in these three counties almost
annually.
Special thanks to our county coordinators for this decade ...
