The present paper gives an account of observations of the passerine birds nesting in associa-tion with some species of birds of prey in central Honshu in 1968-84.<br>1) Of 11 nests of Grey-faced Buzzrard-eagles Butastur indicus, Tree Sparrows Passer montanus, which normally do not occur in the nesting site of Butastur, were frequently observed at 9 nests;9 nests of Tree Sparrows were also found within a radius of several meters of 4 nests of Butastur.Moreover, the Tree Sparrows occurred there only from mid-May to early July, the period of breeding of Butastur.<br>2) Of 6 nests of Honey Buzzards Pernis apivorus, 4 nests were associated with the breeding of the sparrows, whose 2 nests were found very close to the nests of the buzzards.<br>3) At 10 nests of Japanese Lesser Sparrowhawks Accipiter gularis, flocks of Azure-winged Magpies Cyanopica cyana were often observed and 7 nests of the magpies were found within a radius of 10 m at 5 nests of Accipiter.The other 2 nests of the sparrowhawks were abandoned before the magpie started to breed.However, before the abandonment the magpies often visited the nesting sites of the sparrowhawks.<br>5) No passerine birds were observed to breed at or close to 19 nests of Goshawks Accipiper gentilis.
