The authors observed and photographed a 1st winter Bonaparte's Gull Larus philadelphia at Nakaminato City, Ibaragi Pref. on 14 December 1985. It was seen with flocks of Black-headed Gulls Larus ridibundus. This is the first record of the species in Japan.
A single summer plumage White-winged Black Tern Sterna leucoptera was observed at the mouth of the Rekifune River, Taiki, Tokachi Distr., Hokkaido, on 22-23 May 1986. It dove frequently and caught small fish which looked like fry salmon, hovered occasionally, and alighted slowly on the water surface and flew up at once after putting the leg into the water. It appeared that the hovering time of the bird was short compared to a Common Tern Sterna hirundo. Moreover, the bird sometimes showed diving behavior like an Osprey Pandion haliaetus. These habits seemed to be different from those previously reported from Japan (cf. TAKANO 1981).
A single individual of Malay. Night Heron Gorsakius melanolophus was photographed at the estuary. of the Nakagawa River, Anan City, Tokushima Pref., on 30 May 1984. This is the first record of the species in Japan outside of the Yaeyama Islands, southern Ryukyus, where it breeds.
Observations of Latham's Snipes Gallinago hardwickii were made at the Sengokubara Moor, Hakone, central Honshu, from 1975 through 1985. They were seen from early April to mid-September, occurring regularly from late April to mid-June. The numbers of birds counted varied from 0 to 6 individuals, usually 1 or 2. During my observations aerial display was seen only once, on 24 April 1979. The birds I observed seemed to be migrating or non-breeding, although they occur throughout the breeding season and had bred regularly in the highlands of central Honshu until about 30 years ago.
