During a short stay in the Bonin Islands from March 9 to 19, 1988, we identified several food items and recorded the hunting behaviour of the Ogasawara Buzzard Buteo buteo toyoshimai, an endemic subspecies of the Buzzard Buteo buteo. Of six food items identified, five were lizards, Ablepharus boutonii and Anolis carolinensis, and one was a small passerine. Male buzzards hunted from hovering or from perches. The prey was immediately eaten, put on the nest, or fed to the mate on the nest or on a branch.
The White Stork Ciconia ciconia boyciana has ceased to breed in Japan since 1965. However, between 1972 and 1988 there were 23 records of wintering or migrant storks from Hokkaido, northernmost island of Japan. Some of these records may probably represent the same individuals. Thus, at least 12 birds have occurred in Hokkaido since 1972. Although this species also sporadically occurs in Honshu southwards, there is no evidence that the birds observed in Hokkaido flew from the south through Honshu.
A Golden Eagle Aquila chrysaetos nestling (34-36 days old) was found dead in the eyrie in the Hakusan Range of Japan on 8 May 1986. The eaglet was collected, measured and necropsied. It had a massive lesion in the throat (Fig. 2), which extended deep into the tissues of the pharynx and blocked the passageway. Histopathological inspection revealed that the eaglet died of septicemia induced from the wound to the mucous membrane of the pharynx infected with bacteria rather than due to starvation.
An anomalous chick of the Green Pheasant Phasianus c. versicolor with a body and 4 legs was found on 20 May 1985 in the mountain in Kameoka City, Kyoto Pref. It was caught alive as the female pheasant flushed, but died shortly in captivity.
