Great Blue Heron ó Conservation Status

Great Blue Heron populations appear to be stable across the United States and Canada. The birdís primary needs are wetland habitat for hunting and rookery space for breeding, and as a result their populations are susceptible to loss of these habitats. If you are fortunate enough to discover a colony of Great Blue Herons, it is best to observe the birds from a distance. They are sensitive to any kind of rookery disturbance, including noise and nearby human activity, and may abandon nest sites if disturbed.
