Big birds have been regular visitors to the Upper Blackstone Water Pollution Abatement District’s 52 mgd treatment plant in Millbury, Mass.
The tom turkey pictured here is one of a group that regularly patrols the plant grounds looking for food. The red-tailed hawk has made several appearances outside the plant administration building.
The great blue heron fishes in a final settling tank that served the plant before a major upgrade. It is home to shiner minnows that the bird craves. Sharon Lawson, pretreatment coordinator and laboratory specialist for the district, submitted these pictures.
