One source of information is a book:

Trees, shrubs and vines for attracting birds: a manual for the Northeast
by Richard M. DeGraaf and Gretchin M. Witman
Amherst: University of Massachusetts Press, 1979

Also sem the associations page of the North American Native Plant Society

The local groups should be able to guide you to information for your area, 
and plant and seed sources as well.
