The State of the Forest Birds, a paper prepared by Bird Conservation Research, Inc. for the 2011 Connecticut State of the Birds, is now available through the Bird Conservation Contributions web site.  The paper is newly abstracted and updated from its original version, and includes absolute population estimates for a number of species.  The estimates are based on data gathered during the eight year Forest Bird Survey of Southern New England, which employed the variable circular plot technique to survey 148 transects in both summer and winter.  Most notably,  the data showed that several species thought to be rare in Connecticut, such as the Cerulean Warbler, had populations larger and more widespread than previously believed.
