North America's elegant Great Blue Heron is being discovered by biologists to be a remarkably sensitive indicator of the state of our wetlands. If herons are abundant, the wetlands they inhabit form a healthy ecosystem.
In the Florida Everglades, however, agriculture has invaded the wetlands and siphoned off its life-giving water, causing the population of Great Blue Herons and other wading birds to decline by up to 90%. On Vancouver Island a colony of Great Blues failed to raise chicks for two years because dioxins in the effluent from a pulp mill had contaminated their feeding grounds. When the mill was cleaned up, the colony once again flourished. In healthy nesting colonies as many as 400 adults and 1,000 young can create a noisy and spectacular crowd.
The presence of this largest and most widely distributed North American heron reflects the health of its wetland home.
