Found by a contractor who was in the area looking for harvest blocks, this site contains over 30 nests nestled near the tops of white birch, red maple, and trembling aspen. Great Blue Herons are gregarious nesters, meaning that they tend to nest in groups. Great Blue Herons are easily identified as they stand over 1m tall, have a slate blue body, long neck and long, thin legs. These are wading birds, frequenting nearby wetlands and slow-moving streams looking for meals of fish, frogs, shellfish, and even snakes and small rodents at times. Having a large body and a very small tail, Great Blue Herons are not the most graceful of fliers, especially on take-off and landings. As a result, these birds have learned to make their nest within the upper canopy of tall trees to allow for easy access with little fine maneuvering. The nests are a rather crude affair, built of pencil to marker thick twigs loosely piled together. These birds will return to their nesting area year after year, adding more and more layers, with some reaching a depth of a half a meter.
