The great Blue Heron, the largest such bird in North America, is quite adaptable and thrives in various wet habitats. Silent, patient, and often motionless, this majestic bird always makes a spectacular sight. Thanks to its specially shaped neck and extremely good night vision, this wading bird is a quick and skilled fish predator. Since the great Blue Heron accumulates toxins in its body, researchers use it as an indicator of dangerous contaminants in local wetlands. (Bird ID)
