Golden eagles invest much time and effort in bringing up their young; once able to hunt on their own, most golden eagles survive many years, but mortality even among first-born nestlings is much higher, in particular in the first weeks after hatching.
Golden eagles usually hunt during daylight hours, but were recorded hunting from one hour before sunrise to one hour after sunset during the breeding season in southwestern Idaho. [72] The hunting success rate of golden eagles was calculated in Idaho, showing that, out of 115 hunting attempts, 20% were successful in procuring prey. [73]
[6] [35] Nonetheless, studies of the species ecologies show that the Steller's is a more restricted feeder on salmonids and that the Steller's tended to defend a smaller home range area than white-tailed eagles do in the Russian Far East. However, the Steller's appeared to be more flexible in readily switching nest sites between trees and rocky ...
Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year when "winter" conditions (cold or sub-zero temperatures, ice, snow, limited food supplies) make normal activity or even survival difficult or near impossible. In some cases "winter" is characterized not ...
In 2020, there were 316,700 bald eagles in the United States, according to the U.S. Fish and Wildlife Service, a four-fold increase over its 2016 report. The bird was once on the endangered ...

During peak migration season, some visitors to Howard Miller Steelhead Park have reported seeing more than 50 eagles in one day. For those hoping to do more than just stare in awe at the eagles ...
Most wintering birds there appear to be residential adults. Steller's sea eagles that do migrate fly south to winter in rivers and wetlands in Japan, but occasionally move to mountainous inland areas as opposed to the seacoast. Each winter, drifting ice on the Sea of Okhotsk drives thousands of eagles south. Ice reaches Hokkaido in late January.
