UPCOMING

Purple Martin Work, 7 p.m. March 21, Wells

Purple martins are known as harbingers of spring, arriving in Maine in mid-April. But their numbers have been dramatically reduced because European starlings and house sparrows have successfully competed with them for nesting cavities. Throughout the eastern United States, numerous people have been working to support and strengthen their nesting colonies. This program at the Mather Auditorium at the Wells Reserve at Laudholm Farm will reveal work done in New Hampshire and Maine to support these birds. Hosted by York County Audubon, the program is free and open to the public.
