Eagles tend to pick mature trees far from people to build their nests. When roosting, the birds prefer to sit in the highest trees near water sources. Again, these areas are usually isolated from human activity.

 

Eagles require large, undisturbed tracts of forested land near rivers, lakes, and streams, to build their nests. Ideally those nests are 300 to 1,600 feet from any manmade activities or development. Tall and sturdy mature coniferous and hardwood trees can support the huge nests and offer protected areas from which eagles can hunt. Wintering eagles, which do not construct nests here, require that same undisturbed land for safe nighttime roosting. These intact forested areas also protect eagles from wind, rain, and snow, allowing them to stay warm and dry to conserve their energy for hunting.

​

Eagle’s mating season is anywhere from late September to early April, depending on the region. The female lays her first egg 5-10 days after mating with average clutch (group of eggs) is 1-3. The eggs are incubated for about 35 days. Young eagle live with their parents around 10-12 weeks, although fledglings then often stay around "learning from their parents and honing their flying and feeding skills for another 1-2 months.
