The distribution of the Lesser Cuckoo Cuculus poliocephalus in Hokkaido was investigated from late April to early July, 1976‒2016. Surveys were mainly conducted by 2-km-long line transect censusing in 993 quadrats (4.5 km×5 km). In addition, for 526 quadrats, census results obtained from the literature and spot censuses concerning the presence or absence of birds were also incorporated. The Lesser Cuckoo was distributed mainly in Hiyama and Oshima districts and the central part of Iburi district. These results indicate the Lesser Cuckoo to be a common summer visitor in these areas, and an irregular visitor in other areas in Hokkaido.

A vagrant Cinereous Vulture Aegypius monachus was observed in the Kitakami Mountains, Iwate, Northern Honshu, Japan, on December 2, 2015. This is the first record of this species in Iwate Prefecture. During a three-month period after the original observation, the vulture was observed alone six times, at five locations in the Kitakami Mountains up to 50 km apart. At least two of six vultures observed were inferred to be the same juvenile individual.

A white Adélie Penguin Pygoscelis adeliae was sighted in offshore waters of East Antarctica at 65°56′S, 80°39′E on 20 February 2013. This individual had the same morphological characteristics and body size of normal Adélie Penguins, but had entirely white plumage, eyes paler than normal, a brownish to purplish red bill, pale pink legs and feet, and an absence of black coloration on the body. This individual was classified as a possible ‘inolight’ according the color aberration types defined by van Grouw (2013).

. The Copper Pheasant Syrmaticus soemmerringii is endemic to Japan, but nothing is known of its home range. We captured a male Copper Pheasant from the Tama Forest Science Garden in a suburb in Tokyo, Japan, and radio-tracked the bird from June 2003 to May 2004. Vegetation in the study area comprised a cherry arboretum, a mature cedar and cypress plantation, secondary evergreen broadleaved forest, mixed forest with many broadleaved trees invading the coniferous plantation area, and an arboretum planted with various tree species for exhibition. The home range, which was calculated using the minimum convex polygon method based on 138 ‒ 345 points seasonally, was smaller during summer and autumn (5.76 and 5.30 ha, respectively) than that during winter and spring (12.41 and 8.76 ha, respec-tively). The vegetation composition within the home range was significantly different from that of tracked points throughout the year. The bird spent significantly more time in the mixed forest area within its home range throughout the year, and also exhibited a significant prefer ence for the secondary broadleaved forest area throughout the year, except during autumn. However, the proportion tracked points within the cherry arboretum was significantly less than that within the entire home range throughout the year. The tracked male moved around with one female from September 2003 to March 2004, except during February. Two females and the tracked male moved together throughout the day during February 2004.

Abstract. Yoji Yanagihara (1892‒1961) was a bird collector in Gifu, Japan. Yanagihara owned bird specimens which Tokutaro Momiyama (1895‒1962) collected in Hachijojima. Momiyama stayed in Hachijojima from 1922 through 1925 and collected 2,049 bird specimens with his cooperator on the island until 1934. Of these, Momiyama exchanged 100 specimens with other collectors. In this study, I enumerated 16 bird specimens in the Momoyama collection housed at Yamashina Institute of Ornithology, which I consider that Momiyama obtained through exchange with Yanagihara.

Seabirds capture squid in many ways, that mainly involve diving to capture them at the ocean surface or underwater. We present here the first photographic evidence of a seabird, a Red-footed Booby Sula sula, capturing an airborne squid. When a school of squid took flight following disturbance by our boat, a booby flying alongside swooped and approached a flying squid from behind, caught it in the air and ascended quickly. Soon after swallowing the squid, the booby made a plunge-dive and caught another squid that had just landed in the water after a period in flight. Plunge-diving was subsequently repeated over a separate school of squid that had just re-entered the water after flight. Seabirds other than the Red-footed Booby may have frequent opportunities for finding and feeding on airborne squid.
