Stanley Park’s prehistoric herons return

March 19 2024 –

Springtime in Vancouver brings longer days, the bright burst of daffodils and the prehistoric screech of wings in the trees above Stanley Park, which can only mean one thing: the iconic great blue heron colony has officially returned to nest.

High above Park Lane, surrounding the tennis courts, the substantial heron colony has settled into its home for the 24th consecutive year to raise the next generation. 

Last year the colony brought approximately 61 new fledglings into the world, overcoming persistent eagle raids and a delayed nesting season, due to winter weather.

Throughout these challenges, this heron colony has proven to be above all else, resilient. With 80 per cent of British Columbia’s great blue heron population found in and around the Fraser River, the productivity of this heronry has signification implications for the viability of the whole subspecies.

Heron Cam

Now in its ninth year, the Heron Cam provides the ultimate close-up view of this remarkable species as they go about their daily rituals, including courtship and mating, nest building, egg laying, and of course, hatching! Viewers can access a birds-eye view of 40 nests and even take control of the camera by zooming in on multiple nests, using different angles.

Heron Coexistence

To ensure herons are given space to nest and raise their young peacefully, between mid-March to mid-July, visitors should:

  • Observe herons from outside of fenced areas
  • Avoid making loud noises or playing amplified music within 30m of the colony
  • Keep dogs on leash 
  • Refrain from flying drones. Drones are not allowed in parks without a permit, and should strictly not be flown around nesting birds

Report a fallen or injured chick via the Van311 app or by calling 311. Please do not handle any injured wildlife.

About Pacific Great Blue Herons

Pacific Great Blue Herons were first documented in Stanley Park in 1921. Since then, the colony has changed nesting locations several times before settling in its current location in 2001. Vancouver is proudly one of North America’s largest urban heron colonies. 

Pacific Great Blue Herons are federally protected and classified as of ‘special concern’ in British Columbia. The population of these herons has declined steadily since the 1980s as a result of nesting failure, eagle attacks, human disturbance and habitat loss. In Canada, there are around 4-5,000 nesting adults, with the majority living around the Salish Sea. Pacific Great Blue Herons are also unique in that they do not migrate as most great blue herons do.

Heron monitoring

Working in collaboration with the Vancouver Board of Parks and Recreation and the Canadian Wildlife Service, the Stanley Park Ecology Society (SPES) has been supporting herons in this urban environment and monitoring the heronry in Stanley Park since 2004.
