The Ferruginous Hawk is a striking bird of prey that can be found in the grasslands and open areas of Alberta, Canada. As a popular destination for birders, Alberta offers a unique opportunity to observe this magnificent species in its natural habitat. In this article, we will delve into 12 fascinating facts about the Ferruginous Hawk in Alberta, providing birders with a comprehensive guide to understanding and appreciating these incredible birds.
Introduction to the Ferruginous Hawk
The Ferruginous Hawk (Buteo regalis) is a large, dark brown raptor with a distinctive reddish-brown hue on its legs, wings, and tail. It is one of the largest hawks in North America, with a wingspan of up to 1.5 meters (4.9 feet) and a body length of approximately 55-65 cm (22-26 inches). In Alberta, the Ferruginous Hawk can be found in the southern and central regions, where it inhabits grasslands, prairies, and open areas with low vegetation.
Habitat and Distribution
The Ferruginous Hawk is a bird of open country, preferring areas with minimal tree cover and abundant small mammals, its primary source of food. In Alberta, the species can be found in a variety of habitats, including native grasslands, pasturelands, and croplands. The Ferruginous Hawk is a partial migrant, with some populations migrating to the southern United States and Mexico for the winter, while others remain in Alberta year-round.

Diet and Foraging
The Ferruginous Hawk is a carnivorous bird of prey, feeding primarily on small mammals, such as ground squirrels, prairie dogs, and hares. It also consumes birds, reptiles, and insects, making it a versatile and opportunistic hunter. In Alberta, the Ferruginous Hawk can be seen soaring overhead, scanning the ground for potential prey, or perched on a fence post or power pole, waiting for the perfect moment to strike.
Nesting and Breeding
The Ferruginous Hawk is a monogamous species, with pairs forming during the breeding season. The female lays 2-4 eggs in a nest made of sticks, twigs, and other plant material, which is typically placed in a tree or on a cliff ledge. Both parents take turns incubating the eggs and caring for the young, which fledge after approximately 40-50 days. In Alberta, the Ferruginous Hawk breeding season typically occurs from April to July.
Ferruginous Hawk nesting platforms have been installed in various locations throughout Alberta, providing the species with a safe and stable place to breed and raise its young. These platforms have been shown to increase nesting success and reduce the risk of nest failure due to predation or human disturbance.
| Nesting Category | Data |
|---|---|
| Clutch Size | 2-4 eggs |
| Incubation Period | Approximately 30-35 days |
| Fledging Period | Approximately 40-50 days |
| Breeding Season | April to July |
Conservation Status
The Ferruginous Hawk is listed as a species of special concern under the Alberta Wildlife Act, due to habitat loss and fragmentation, as well as the decline of its primary food source, the ground squirrel. Conservation efforts are underway to protect the species and its habitat, including the creation of protected areas and the implementation of sustainable land-use practices.
Threats and Challenges
The Ferruginous Hawk faces several threats and challenges in Alberta, including habitat loss and fragmentation, climate change, and the decline of its primary food source. Habitat fragmentation can make it difficult for the species to find suitable nesting and foraging areas, while climate change can alter the availability of prey and breeding habitat. The decline of the ground squirrel population, due to habitat loss and disease, has also had a significant impact on the Ferruginous Hawk population.
Collaborative conservation efforts are necessary to protect the Ferruginous Hawk and its habitat in Alberta. This includes working with landowners, conservation organizations, and government agencies to create protected areas, implement sustainable land-use practices, and monitor the species' population trends.
