The Second Breeding Bird Atlas of Vermont (2003-2007)

The Vermont Breeding Bird Atlas (VBBA) is one of the most comprehensive bird surveys in Vermont. It is completed once every 25 years during a 5-year period. Data collection for the first and second atlases were in 1976-1981 and in 2003-2007, respectively. The main goal of the first atlas was to document the spatial distribution of each bird species at a broad geographical scale. The goal of the second atlas was to survey the same lands in Vermont that were surveyed during the first atlas in order to detect changes in the distribution and status of species. In addition, in the second atlas the amount of land surveyed was doubled.
