Great Blue Herons – Methuen Rookery
April 1, 2014 in Nearby Waterbirds
The Great Blue Herons nests in large colonies with many other mated pairs. These colonies are usually in forested wetlands or on islands with trees. The herons build large nests of twigs high in the trees to discourage predators, such as raccoons and snakes. The nests are often 3 feet across and almost as tall. The colonies are easily recognized by the many groupings of nests scattered throughout the trees. The Methuen Rookery is busy with courtship activities and nest building!
