In Nov.1994, the Japn Falconers Association constructed two manmade nests for Goshawk in the hilly districts of the western part of Tokyo. One was used by a pair of Goshawk during the 1995 breeding season. The nest (Fig.1), about 1m in diameter, was set at the height of about 18m in a fir tree. The pair succeeded in laying egg and having them hatch, but the young were lost before leaving the nest.
