Bald eagles are large birds of prey that are native to North America, including Colorado. They are known for their distinctive white head and tail feathers, which are not present in young birds until they reach maturity at around 4-5 years of age.
Bald eagles typically live near water, and can be found along rivers, reservoirs, and coastlines. They are opportunistic hunters, and will eat a wide variety of prey, including fish, waterfowl, and small mammals. They are also known to scavenge for food when necessary.
In Colorado, Bald eagles are known to breed in the high country and migrate to lower elevations during the winter. They can be found in the western part of the state, along the Colorado River and in the San Luis Valley.
Bald eagle populations were once seriously threatened by habitat loss and the use of the pesticide DDT, but thanks to conservation efforts, the species has made a comeback in Colorado and across North America. The Bald eagle was removed from the federal list of threatened and endangered species in 2007.
Golden Eagle
Golden eagles are large birds of prey that are native to North America, including Colorado. They are similar in appearance to bald eagles, but have dark feathers on their head and tail, and are generally smaller.
Golden eagles are found in a variety of habitats, including mountains, grasslands, and deserts. They are primarily hunters of small mammals, such as rabbits and ground squirrels, but will also take larger prey such as deer and pronghorn.
In Colorado, Golden eagles are known to breed in the high country, and migrate to lower elevations during the winter. They can be found in the western part of the state, along the Colorado River and in the San Luis Valley.
Golden eagle populations have been stable in recent years, but the species is considered a species of concern in some areas due to habitat loss and human disturbance.The American kestrel (Falco sparverius) is a small falcon that is native to North America, including Colorado. They are the smallest and most common falcon in North America and one of the most colorful birds of prey. The males have a blue-gray head, rusty back and tail, and a rusty breast with black spots, while the females have a rusty back and tail with a white face and rusty breast with black spots.
