When they used seaweed to build the nests, the water dripped on the power lines which short-circuited with disastrous results. To stop this, the power companies put up platforms that were made for osprey or other birds. Workers then could climb up to put the backpacks on the ospreys so when they flew away they could be tracked. Ospreys usually lay two to four eggs. Feeding Habits Ospreys are usually noted for their feet-first plunge into the water, especially when catching fish.
Ospreys usually eat only fish.
Osprey feet are specially adapted for catching and grasping fish. After the bird catches the fish, it carries it in a head first orientation back to the nest. The osprey gets its food mostly in shallow waters. The osprey may go under the water but it does not dive deep. It comes out of the water with a fish in its clasped feet.
