Ospreys live throughout the world, in watery spots like marshes, rivers, and seas. Their diet is pretty much exclusively fish, which they dive for from up to 120 feet. but when fish is not available, ospreys will eat lizards or small mammals.Osprey nests are made of sticks and put on all sorts of things, like trees, cliffs, and man-made structures; so long as it's near water. These nests are re-used year after year, and sticks are added to them. Nests can get to be huge: more than seven feet across and five feet deep.
A clutch of 2-4 eggs are layed at one time, and incubated over a period of 35-40 days. Chicks mature at 3 years of age.
