The earliest known record of these magnificent birds dates back to a 1921 photo by Leonard Frank of a colony near Brockton Point. It is quite likely that the birds inhabited Stanley Park years before this image was captured, too. Even back then, people were fascinated by the great blue herons.
For almost 100 years, herons have called Stanley Park “home”.
Location of the colony
The location of the colony has changed a few times since 1921. When and why the herons change nesting locations is not fully understood.
Other locations of nesting trees after Brockton Point include:
- By the aquarium
- Around Beaver Lake
- Near the zoo
- Beach Ave near the Vancouver Park Board offices (current location)

Records of the Stanley Park heron colony begins
An article in the Province newspaper shows a tree located between Brockton Point and Lumbermen’s Arch. Herons were said to hatch in May and fledge in August/September. Total nests: 39.
Heron colony at Beaver Lake
Limited Canadian Wildlife Service (CWS) data indicates the herons at one time built a new colony at Beaver Lake. CWS records describe 37 nests in a single large spruce tree at Brockton Point in 1967.
Heron colony moves to the area around the Vancouver Aquarium
Maximum number of nests recorded was in 1978 (44 nests). Eagle predation is significant at this location.

Herons abandon zoo area of the park
Some attributed the zoo abandonment to construction activity, but no formal studies were made about other sources of disturbance or habitat loss.
Herons move to Park Board Office area near 2099 Beach Ave
Protective fencing is installed around the nest tree to minimize human disturbances
Predator guards are installed on nest trees. Racoon predation decreased dramatically.
