Mass Audubon's 28th annual Bird-a-thon took place May 13-14, 2011 and raised more than $175,000 for our wildlife sanctuaries and programs. For more information, visit http://www.massaudubon.org/birdathon.
Some 633 birders on 26 teams scoured the state for 24 hours on May 13th and 14th in search of the most species they could see or hear.
