On Saturday, March 7, The Trustees of Reservations will offer a training session for volunteers interested in helping to monitor bluebird nest boxes this coming spring. The Trustees protect many properties with open fields that provide an ideal breeding habitat for rare species including Eastern Bluebirds. There are dozens of volunteer-built bluebird boxes on several properties along the South Coast that provide critical nesting spots for these beautiful birds. Bluebird trails have been established in Fall River, Westport, Dartmouth and Rochester and volunteers are needed to check the boxes regularly during the nesting season to keep track of the bluebird population and discourage non-native House Sparrows that force native birds out. A free workshop for those interested in learning more will be held between 1:00 and 3:00 pm at the Westport Town Farm located at 830 Drift Road in Westport. To register, go to www.thetrustees.org/volunteer, email kheard@ttor.org, or call 508-636-4693 ext. 5003. Come learn how you can participate in this ongoing project to bring back the Blues.
