Local naturalist Brian Keating quickly identified two bald eagles by the river at Carburn Park in southeast Calgary, noting that this pair has been nesting in the area for many years. He emphasized the likelihood of spotting eagles in the park due to the ideal habitat provided by the Bow River, which has led to an increase in eagle sightings in the province.
Bald eagles have expanded their presence in Alberta, from the Bow River to the grasslands, with managing director Colin Weir from the Alberta Birds of Prey Foundation highlighting the noticeable growth in their population over the past decade. He mentioned that the rivers in southern Alberta offer excellent nesting grounds for these birds, with abundant food sources like fish and migratory ducks.
The province’s bald eagle population consists of both year-round residents, such as those in Calgary during the winter, and migratory birds that nest in places like Banff but spend the winter in warmer regions. Additionally, bald eagles have been observed in unexpected locations, like agricultural areas, where they scavenge on dead livestock.
Recent data from the local Christmas Bird Count in Calgary revealed a significant increase in the number of bald eagles, reflecting the positive conservation efforts and population growth. NatureCounts, a platform tracking wildlife sightings, indicates a rise in bald eagle populations across North America, following conservation measures that have led to their removal from the endangered species list.
Despite the success in bald eagle conservation, these majestic birds still face threats in Canada, including poaching, habitat loss, and environmental contamination. Keating highlighted lead poisoning as a significant concern for bald eagles, stemming from exposure to lead through contaminated prey and fishing lures. Conservationists continue to work towards protecting these iconic birds and their habitats.
