By Larry ChaseOut on a limb on East Andover’s Emery Pond in late August was this Great Blue Heron, seen here admiring itself in its reflection. According to the Audubon Society’s Guide to North American Birds, “Widespread and familiar (though often called ‘crane’), the largest heron in North America. Often seen standing silently along inland rivers or lakeshores, or flying high overhead, with slow wingbeats, its head hunched back onto its shoulders.” Caption and photo: Larry Chase
