Brackendale Winter Eagle Count

Each January, the Squamish Environment Society coordinates a single-day volunteer count of bald eagles wintering along a 40-mile stretch of the Squamish, Cheakamus, and Mamquam Rivers near Brackendale. Dozens of trained counters are stationed at fixed census points at dawn and tally every eagle visible from first light. Results are submitted to a central database that has tracked eagle populations here since 1986, making this one of the longest continuous raptor monitoring programs in British Columbia.

Brackendale's prominence on the eagle calendar is tied directly to the chum salmon run. From late October through January, exhausted and dying chum carpet the gravel bars of the Squamish River, providing an extraordinary concentrated food source. Eagles gather from across BC and the Pacific Northwest to exploit this feast. The record count, set in January 1994, reached 3,769 eagles in a single day — a North American record at the time. Counts today typically fall between 500 and 2,000 depending on salmon run strength.

The count day itself is a community science event open to anyone willing to spend several hours outdoors in January cold. Experienced birders mentor newcomers, and all observers contribute to data that feeds into provincial raptor management reports. The Squamish Environment Society releases the official count results publicly within days, and they are archived alongside four decades of comparable counts.

Count day begins before sunrise. Volunteers arrive at assigned stations along the river dike trails between Brackendale and the Squamish estuary, set up spotting scopes, and begin tallying as light allows. The atmosphere is part scientific expedition and part community gathering — thermoses of coffee, shared binoculars, and the constant commentary of experienced observers helping identify distant perched birds from juveniles. Eagles are visible from the roadside and from public dike trails even without joining an organized count team.

Outside count day, the Brackendale Eagle Reserve — a protected area of cottonwood gallery forest and gravel bar managed by BC Parks and the Squamish Environment Society — is open year-round. The peak viewing window runs from mid-November through late January, when you can park at the Brackendale Art Gallery trailhead and walk the dike trail unguided. Eagles line the cottonwood canopy like heavy ornaments, sometimes a dozen birds in a single tree. Bring a scope or at minimum 10x binoculars; a spotting scope on a tripod transforms the experience.
