Eagle Migration Count Spring 2023
This site is located along a major Golden Eagle flyway and their migrations can be tracked from the same place in spring and autumn. This monitoring site is managed by the Rocky Mountain Eagle Research Foundation. Monitoring site is manned by volunteers. Migration is more pronounced on days with SW and W winds. The count is conducted from Sept 20 to Nov 15 in the fall, and from Mar 1 to Apr 22 in the spring. The location in Hay Meadow, along the banks of the Kananaskis River offers 360 degree views of the surrounding ridges, which the eagles and other raptors follow on their migration both spring and fall.
The Hay Meadow site is located in the valley of the Kananaskis River in the front ranges of the Canadian Rockies. To find the monitoring site, take the TransCanada Highway (Highway 1) west from Calgary, and drive S on Highway 40 (Kananaskis Trail) for ~25 km. Turn right at the sign for Kananaskis Village and Nakiska, and drive W for 1 km. Pass the turn to Kananaskis Village on the left and almost immediately turn right onto a good gravel road. The turning is sign posted "Stoney Trailhead." A parking area is just a few hundred m down this road. Park in the parking area and walk past the gate. Take the first trail to the right through the forest. The site is 1 km from the parking lot down this trail.
Rocky Mountain Eagle Research Foundation
Since 1992, Rocky Mountain Eagle Research Foundation (RMERF) volunteers have performed annual raptor migration counts at the same site location in the Kananaskis Country, Alberta, spring and fall; significantly providing data for the understanding of and amazement in watching migrating Golden Eagles.
