Why are bald eagles becoming more common in Alberta? This question has sparked curiosity and intrigue among nature enthusiasts and conservationists alike. In this article, we'll explore the fascinating journey of these iconic birds and the factors contributing to their increasing presence in the province. But here's where it gets controversial...
Once considered a nuisance and hunted in vast numbers, bald eagles have experienced a remarkable resurgence in North America, including Alberta. The story of their conservation success is a testament to the power of human intervention and the resilience of these majestic creatures. And this is the part most people miss...
In the 1970s, the United States government designated bald eagles as an endangered species, which had a significant impact on their population recovery. However, the real turning point came with the ban on the highly destructive pesticide DDT and the legal protection against killing bald eagles in the U.S. in 1940. These measures, along with conservation initiatives, have played a crucial role in their comeback.
Alberta's Wildlife Act prohibits hunting and harassing bald eagles, but they still face threats like poaching, habitat loss, and environmental contamination. Lead poisoning, for instance, is a serious concern due to hunters shooting animals with lead ammunition, which contaminates carcasses and fishing lures. Despite these challenges, the bald eagle population in Alberta has been steadily increasing, with more than 400 spotted in Calgary alone during the latest Christmas Bird Count.
The Bow River and its surrounding areas offer an ideal habitat for bald eagles, providing ample food sources like fish and migratory ducks. Additionally, the province's diverse landscapes, from grasslands to mountain rivers and lakes, have contributed to the expansion of their habitat and population. As a result, spotting these iconic birds of prey is becoming more commonplace across Alberta, offering a glimpse into the success of conservation efforts and the resilience of nature.
