There's a new resource for understanding Vermont's bird populations.
Governor Peter Shumlin on Wednesday helped mark the publication of a new book, "Second Atlas of Breeding Birds of Vermont".
The book was produced over a decade with the help of 350 volunteers who donated 30,000 hours compiling the information.
Some of the changes noted since the publication of the first atlas include declines in some grassland bird species such as upland sandpipers or grasshopper sparrows.
But other species have increased, such as the tufted titmouse and the wild turkey.
The Vermont Center for Ecostudies says the book will become a classic reference for birders, ornithologists, conservationists, land use planners and others.
