When do bald eagles lay their eggs in the northeast?

Eagles lay their eggs when they are fully mature. For example, a bald eagle lays its eggs when its about 4-5 years. Steller's sea eagles also mature at around the same time, but wait to lay their eggs at the time when their feathers change color from brown to black, which takes another few years. However, if you're asking about the season in which eagles lay their eggs, it's usually spring, which differs in months in different places. For example, in North America, bald eagles lay their eggs at around May, the springtime in that place.
