On Saturday, May 25, Maine Coast Heritage Trust (MCHT) invites the public to enjoy a morning outdoors exploring birds’ habitats and building bluebird 

nest boxes at Erickson Fields Preserve, 164 West Street in Rockport. The day will begin with an 8 a.m. bird walk led by MCHT steward/naturalist Kirk Gentalen. He will guide participants around MCHT’s Teen Ag garden and through the woods in search of migratory songbirds — warblers, thrushes, vireos, sparrows — and to discover what other feathered creatures inhabit the preserve. The bird walk will be followed by a 10 a.m. bluebird nest box workshop in which naturalist John Twomey will provide materials and guidance for participants to build boxes to take home. Both the bird walk and the workshop are free, but registration by May 22 (for one or both) is recommended, as space is limited. For more information and to register, email Joelle Albury at jalbury@mcht.org. Pictured left to right, bluebird nest box being checked out by tree swallows; a Northern Parula.
