    Bird banding and toracing research was conducted in the southern part of the Akaishi Mountains (on an approximately 10 km area of ridge between from Mt. Izaruga to Mt. Hijiri), during a 19 day period from June to December, 2007 and a 10 day period from June to July, 2008. Five territorial adult males, three adult females and one juvenile female of Ptarmigan Lagopus mutus japonicus were captured. All of the captured birds, except for one adult female that was blind in the right eye, were banded and released. Five of the banded birds were confirmed in the follow up research, including three that were observed about a year after release. A team from Shinshu University also conducted similar research in the same area in 2005, and banded and released seven adult males and three asult females. This research confirmed two of these banded males and one female. All of the observations were in the general vincinity of where the birds had been released.

    A total of 10 frozen Japanese Cormorant Phalacrocorax capillatus carcasses were obtained from various sources. Dissection and inspection of sexual glands allowed a reliable confirmation of sex for all specimens. The sample included 6 males and 4 males. A total of six measurements: Exposed culmen length (ECL); Greatest height of bill at angle of gonys (GHBG); Greatest width of bill at angle of gonys (GWBG); Length of bill from gape (LBG); Tarsus length (TL) and Natural wing length (WL); were then taken for each of the sexed specimens. The results showed that males are significantly longer than females in terms of LBG and WL.

    This paper reports an observation of predation by Japanese Spparowhawk Accipter gularis on the fledgling of a Red-flanked Bluetail, a ground nesting species. The predation was observed at the 5th station of Mt. Fuji, in Subashiri, Shizuoka prefecture. The Red-flanked bluetail had just fledged that day, and was hiding under a dead tree when taken by the Sparrowhawk. The sparrowhawk was clearly identified as the predator after being caught in a mist-net along with the dead bluetail.
