In Our Backyard: Great Blue Heron


The great blue heron (Ardea herodias) embodies grace and tranquility… except when it is heard squawking! It is an iconic and recognizable bird, known for its towering stature and striking appearance. With its long, sinuous neck, gray-blue plumage, and dagger-like beak, this heron stands as a symbol of patience and adaptability.

The great blue heron is a widespread species that can be found across North America, including the Thompson Watershed. These magnificent birds thrive in diverse habitats such as wetlands, rivers, lakeshores, and coastal areas. They are often observed in proximity to freshwater habitats, where they seek food and establish their nesting colonies.

These birds play a vital ecological role in the Thompson Watershed. As opportunistic feeders, they primarily consume fish, amphibians, and small mammals, helping to regulate local populations and maintain the delicate balance of aquatic ecosystems. Their presence is indicative of the overall health and diversity of the region’s wetland and riparian habitats.

While the great blue heron is not currently considered endangered, it faces various threats that impact its population in the Thompson Watershed, including habitat loss and degradation, disturbance, and urbanization.

“We have it within us to take the courage that is needed…to transform and change our way of living.”

Stó:lō Nation Elder Eddie Gardner.

Establishing protected areas, wildlife refuges, and reserves provide sanctuaries for the great blue heron and other species. These designated areas offer undisturbed breeding grounds and foraging sites, helping to safeguard the species’ well-being.

A notable example of habitat restoration and protection that benefits the great blue heron and other species is the story of the Great Blue Heron Nature Reserve in Chilliwack, BC. Check out this great documentary on the sanctuary and how its keepers are working to provide valuable habitat to many of BC’s important species.


The great blue heron serves as a symbol of the Thompson Watershed’s rich natural heritage and the delicate balance between human development and environmental conservation. By valuing and protecting its wetland habitats, we can ensure the continued presence of this majestic bird, enriching our lives and maintaining the integrity of our region’s ecosystems.
