Golden eagles are North America's largest predatory bird. They are monogamous and may maintain pair bonds for several years. Golden eagles breed from March through August, depending on their geographic location. The nests are made up of sticks and vegetation (conifer boughs, grasses, barks, leave, mosses, lichen, fur, bones, antlers, and human-made objects). On average eggs per season 2 and range, time to hatch is 35 to 45 days. Female golden eagles are primarily responsible for incubation, though males may do some of the incubation. Golden eagles can carry up to 8 pounds during flight. Generally, the male delivers most of the food to the nest, while the female usually feeds the young. They can fly up to 80 mph, though the average speed is 28-32 mph, and may reach speeds up to 200 mph while they are diving. They use nine different calls to communicate.
Humans are the greatest threat to Golden Eagles. It is estimated that over 70 percent of deaths of Golden Eagles are attributed to human impact, either on purpose (shooting, trapped, or poisoned), or because of human activities adversely impacting the environment. High–voltage power poles and power sources that are not visible in poor weather conditions also pose a threat to raptors. Encouraging utility companies across the country to implement avian-friendly alternatives to their power poles and lines could voice to save these birds of prey. Educating and imparting knowledge about the economic importance of these birds would play a great role to save them. Some of the conservation efforts initiated are utility to enhance avian populations or habitat, developing nest platforms, managing habitats to benefit migratory birds, or working cooperatively with agencies or organizations in such efforts. Where feasible, such proactive development of new ideas and methods to protect migratory birds should be encouraged and explored.
