The September issue of the Journal Science, included an article that highlighted a study showing an alarming decline in bird populations throughout North America.  Similar studies in Europe have found the same.  The report indicates a net population decline of 29% (about three billion birds) in North America since 1970.  Yes that’s billion, with a “b”.  Iain MacLeod, Executive Director of Squam Lakes Natural Science Center, took a closer look at long term bird data in New Hampshire’s North Country and found similar declines.  Join Iain for an evening of exploring and explaining these trends and what they mean for the future of New Hampshire’s avian and greater wildlife populations.
