日本では風力発電の普及にともない，風車が鳥類に影響を与える問題が懸念されている．影響の種類は，鳥類が風車にぶつかる「衝突」，風車周辺からいなくなる「生息地放棄」，渡りや移動の経路を阻害する「移動の障壁」の3 つがある．衝突は今まで国内で341 羽が発見され，トビ，オジロワシ，カモメ類，カラス類が多い．生息地放棄は京都府と三重県の例があり，いずれも風車周辺で鳥類の生息密度が減少した．移動の障壁は愛媛県のハチクマ，長崎県のナベヅル・マナヅルの例があり，いずれも風車建設後に飛翔経路が変わった．今後，日本では事後調査を積み重ね，どのような風車が鳥類に影響を与えるのか研究をさらに進めるべきである．

We observed a Blue-tailed Bee-eater Merops philippinus on 7 July 2013 in Hachijo-jima Island, southern Izu Islands, central Japan. The individual was perched on an electric cable at the edge of a forest. It had greenish brown plumage, a black eye stripe, a pale blue moustachial stripe and a long black bill. Since the bird had elongated central tail feathers typical to bee-eaters, it was assumed to be adult. This is the first record of a Blue-tailed Bee-eater in Japan, which probably visited the island accidentally.

Although the Daurian Redstart Phoenicurus auroreus is currently classified as a winter visitor in Japan, we collected 13 nests of this species in Mt. Yatsugatake, central Japan. They were all bowl-shaped with a base extending to one side. The confirmed breeding nests had an outer diameter of an average of 129mm, an inside diameter of an average of 73mm and a depth of an average of 31mm. They were composed primarily of fine roots, bryophyta and grass stems with animal hair, feathers and grass leaves built into them. Many of the nests had a nest cup lined with animal hair on fine roots. The basal part of many nests was also built mainly of bryophyta, fine roots, grass stems, twigs and tree leaves.

On May 22, 2014, I observed a Fairly Pitta feeding at the edge of an evergreen forest in Miyake Island of the Izu Islands. This bird stayed in the island for at least seven days. This is the first record of this species observed in the Izu Islands.
