Great Blue Heron Rookery June 5, 2011

The Lyons-Cutler Reservation, located along Allowance Brook in Sudbury, contains wetlands and beautiful red maple, mixed oak and white pine uplands. The upland forest descends gently to a swamp with a Great Blue Heron rookery where we can get very close views of the domestic life of the herons and hear their growling offspring. Around the swamp we could also see Eastern Kingbird, Eastern Phoebe, Tree and Rough-winged Swallow, Red-Winged Blackbird, Kingfisher, Swamp Sparrow, Northern Flicker, and Eastern Bluebird. The hike through the woods could produce several species of warblers, Wood Thrush, Brown Creeper, Baltimore Oriole, Brown Thrasher, Blue-Headed Vireo, and migrating flycatchers of various species. - - Open to anyone age 16 or older. A map to meeting site will be sent to registrants. Registration is required. Call 781-259-2200 for details.
