FOREST BIRD POPULATION ESTIMATES NEARLY COMPLETE


Final computations of the regional populations of Connecticut and Rhode Island’s forest birds are presently underway.  This is, however, only one aspect of the ongoing analysis of the enormous quantities of data gathered during the Forest Bird Survey of Southern New England.  Upcoming analyses include characterization of the habitats of Rhode Island and western Connecticut as well as analysis of the relationship between habitat and bird populations. When complete, our analyses will result in the publication of Forest Birds of Connecticut and Rhode Island.
