We found a pair of Ospreys Pandion haliaetus nesting near to a site of road construction. We attempted to induce them to use an artificial nest away from the construction site so that they can breed safely. In 2004, an artificial nest made of many branches was placed on the top of each of three red pines, Pinus densiflora, located near to the natural nest of the pair. In 2005, the pair utilized one of these artificial nests, which was located 175 m from the natural nest. Our attempt to induce the pair to a safer location succeeded. The conservation by installing an artificial nest can be effective.
