Food fights between big birds may be in the offing near the Cedar River in Iowa.
Officials are erecting two nesting platforms for ospreys along the river. The platforms are part of a larger effort to restore ospreys to the state.
But the new platforms are going up in an area frequented by bald eagles, which are another big bird that preys on fish. The eagles are known to rob ospreys and even other eagles of their fish.
Bird biologist Bruce Ehresman says ospreys and bald eagles can occupy the same area and have been doing well together at Don Williams Lake in Boone County, where the fish supply apparently is plentiful.
