Yes, there are golden eagles in Colorado. They are known to inhabit open and semi-open rangeland across the northern hemisphere, including Colorado. A rare tree nesting pair of golden eagles has sparked a debate over open space rec trails and protecting wildlife around Loveland. Additionally, a pair of golden eagles has returned to Colorado National Monument for at least the third year in a row to nest this winter.
The Majestic Golden Eagle
Golden eagles have a remarkable capacity for soaring with a wingspan known to exceed seven feet. They are known as “King of the Birds” and have a remarkable eye structure that allows them to see a mouse’s whiskers twitch at nearly 2 miles away. Their primary prey includes mice, rabbits, and snakes, but they are also opportunistic and known to scavenge heavily.
Distinguishing Golden Eagles from Bald Eagles
There are 59 different species of eagles worldwide, with only two species in North America, including the golden eagle. Golden eagles can be differentiated from bald eagles by their characteristic golden “casting” on their neck and head feathers, white patches on a young golden eagle’s wings and base of tail, feathering all the way down the leg, and a smaller bill than that of the bald eagle. Additionally, golden eagles prefer open rangeland, while bald eagles tend towards access to water.
Golden Eagles in Colorado
In Colorado, golden eagles are known to nest in rocky cliffs and prey on rabbits, snakes, and prairie dogs. They are very territorial, with a pair nesting at South Table Mountain and North Table Mountain considered their territory. To protect nesting raptors during breeding season, Jeffco Open Space imposes partial closures on both mesas and at six other locations, ranging from February to July.
Challenges Faced by Golden Eagles in Colorado
In 2022, three wild adult eagles in Colorado died from Highly Pathogenic Avian Influenza (HPAI), including one female tagged for CPW’s research study. HPAI was responsible for a 20% drop in nest success that year, with eaglets being more susceptible to the disease than older birds. However, detections have been much lower so far in 2023, and it is hoped that it will be a better year for bald eagles and other birds impacted by HPAI.
Conclusion
Golden eagles are a majestic and iconic species found in Colorado’s open and semi-open rangelands. While they face challenges such as the impact of HPAI, efforts are being made to protect their nesting sites and ensure their continued presence in the state. As we appreciate the beauty and power of these magnificent birds, we must also work to preserve their habitat and ensure their long-term survival.
