The size of an osprey nest can vary considerably, but they are typically around 2-3 feet in diameter and 1-2 feet deep. The nest is built by both the male and female osprey, and it can take several weeks to complete. Once the nest is built, the female osprey will lay her eggs, which are typically white with brown spots. The eggs are incubated for about 35 days, and the chicks will hatch and fledge from the nest after about 60 days.
Osprey nests are typically reused by the same pair of ospreys year after year. However, if the nest is damaged or destroyed, the ospreys will build a new one.
