The Snake River provides abundant fish and waterfowl, making it an ideal location for Bald Eagles, which primarily feed on fish. Golden Eagles, which prey on a variety of mammals and birds, may nest in rocky outcrops along the river.
The Golden Eagle is another magnificent raptor species found in Idaho. They are primarily found in the western and mountainous regions of the state, especially in areas with rugged terrain. Golden Eagles are known for their golden brown plumage and large size, with a wingspan that can reach up to 5 feet.
They prefer open country, such as deserts, cliffs, and mountainous areas, where they hunt a wide variety of prey, including mammals like rabbits and ground squirrels, and birds. Golden Eagles are known for their powerful flight and keen eyesight, which they use to spot prey from great heights. These eagles are skilled predators and are considered one of the top raptors in the avian hierarchy.
Both the Bald Eagle and Golden Eagle are significant and treasured species in Idaho, with the Bald Eagle being particularly symbolic as the national emblem of the United States. Observing these majestic birds in the wild is a thrilling experience for birdwatchers and wildlife enthusiasts in Idaho.
Hawks are a diverse group of birds of prey found throughout Idaho, and they play an essential role in the state's ecosystem. A few common species of hawks in Idaho include the Red Tailed Hawk (Buteo jamaicensis), one of the most widespread and well known hawks in North America. These hawks are recognized by their striking red tails, but not all individuals have the same coloration. They are often found in open country, grasslands, and along roadsides, where they hunt rodents and small mammals. Red Tailed Hawks are known for their distinctive, high pitched scream often heard in movies, although their actual call is quite different.
Swainson's Hawks are migratory raptors that visit Idaho during their breeding season. They are identified by their light plumage, especially on the belly, and a distinctive "bib" or dark patch on their throat. These hawks feed primarily on insects and can often be seen catching insects on the wing during their migration. They nest in trees or tall structures and are known for their impressive migrations from South America to North America.
These hawks are known as "accipiters" and are characterized by their short wings and long tails. Cooper's Hawks are slightly larger and are often seen in wooded areas, where they prey on birds and small mammals. Sharp Shinned Hawks are smaller and more agile, specializing in hunting songbirds. Both species are skilled hunters in wooded habitats.
The Ferruginous Hawk is the largest hawk species in North America and can be found in the drier and open regions of Idaho. They are recognized by their rusty or "ferruginous" plumage on the legs and some individuals have a distinctive white face. Ferruginous Hawks primarily prey on small mammals, particularly ground squirrels and prairie dogs.
The Roughlegged Hawk is a winter visitor to Idaho, often seen in open areas and farmlands during the colder months. They are named for their feathered legs, a characteristic not typically seen in other hawks. Rough Legged Hawks primarily feed on small mammals and rodents.
Hawks are apex predators that help control rodent populations and maintain the balance of ecosystems. Observing these birds of prey in the wild can be a thrilling experience for birdwatchers and nature enthusiasts in Idaho.
Falcons are a group of raptors known for their speed, agility, and sharp talons. Several species of falcons can be found in Idaho. Here are some of the common falcon species in the state. The Peregrine Falcon is one of the most well known falcon species, renowned for its incredible speed and aerial hunting abilities. These birds have distinctive dark markings on their heads and a bluish gray coloration on their wings and backs.
Prairie Falcons are medium-sized falcons with pale plumage and streaked underparts. They are typically found in arid regions, grasslands, and cliffs. Their primary prey includes small mammals and birds. Falcons are admired for their hunting prowess and are often used in falconry, a hunting tradition that involves using trained falcons to capture game. Observing falcons in the wild can be a thrilling experience due to their speed and aerial acrobatics.
Peregrines are often seen hunting birds in open skies, using their swift dives and high speed stoops to capture prey midair. In the past, the Peregrine Falcon was an endangered species, but extensive conservation efforts have helped their populations recover, making them a success story for conservation in Idaho and across the United States.
