Due to the large size of Osprey's nests and the height at which they nest, it is often found that other small birds will occupy parts of the nest. Since Osprey migrate for breeding, parts of the year their nests remain unoccupied by the larger birds, allowing time for smaller bird species to take up residence. The Osprey commonly reuse their nests and maintain its upkeep.
