Craig Smith photographed the following at the Assabet River National Wildlife Refuge in Maynard and Sudbury: an American robin, a cedar waxwing, a chipping sparrow, an eastern chipmunk, an eastern phoebe, a gray catbird, a great blue heron with a red-winged blackbird, an indigo bunting and a red-winged blackbird.

Steve from Stow photographed an indigo bunting and an American goldfinch at his backyard feeder, as well as a chipping sparrow feeding a young brown-headed cowbird. Brown-headed cowbirds don't build nests, instead the females lay many eggs each year, depositing them in other birds' nests. The resulting chicks are often larger than the host parents' chicks and have a competitive advantage in the nest.

 

Craig Smith photographed several species of birds and a butterfly at SVT's Cedar Hill Reservation in Northborough: blue-winged warbler, cedar waxwing, common ringlet, common yellowthroat, eastern towhee, house wren, indigo bunting, northern flicker, ruby-throated hummingbird.
