Ospreys build nests at the tops of trees, and oftentimes on man-made structures, such as telephone poles, service towers, or nest platforms made specifically for it. Established pairs oftentimes return to previous nest sites.
On average, ospreys lay three eggs, but they can lay one to four eggs. They only lay one clutch per season, regardless of whether the original clutch is taken or destroyed.
Young osprey chicks start fledging around 7 to 8 weeks old.
Ospreys are piscivores, meaning they almost exclusively eat fish. This is how they got the nickname "fish hawk." Ospreys hunt in both fresh and saltwater.
