In order to make smart and effective conservation choices, we need a good understanding of how the birds of Massachusetts are doing, and where they might need concentrated attention. Mass Audubon maintains the most comprehensive public database of bird distribution, abundance and trend information for the Commonwealth, a resource that is used by conservation partners and concerned citizens alike. This wealth of information is kept current through our long-term monitoring and research programs.
