オオワシ Steller's Sea-Eagle
オオワシは日本で見られる最大の猛禽類です。営巣・繁殖はシベリア極東地方で、流氷シーズンは越冬で日本に飛来してきます。
翼を広げると実に2.5m、体重は7.5kgもあります。
白と黒のツートンカラーで粋な井出たちで、世界中のバードウォッチャーがこの極寒の知床まで来るのもうなづけます。
オオワシの生息数は5000-7000羽で絶滅危惧Ⅱ類に指定された貴重な野鳥です。
These very large, powerful eagles are also striking in appearance. They are dark but dramatically colored with white tail, shoulders, rump, thighs and forehead.
These eagles are believed to breed only in far eastern Russia, along the coasts and surrounding islands of the Sea of Okhotsk and Bering Sea. They are most common on the Kamchatka Peninsula.
Each winter, many Steller's sea eagles migrate from their breeding grounds to Japan, and a few reach Korea or even farther afield. Other individuals do not migrate, but simply move to open water as winter approaches.
Steller's sea eagles do not occur in large numbers(about 5000-7000 numbers), but their populations appear to be stable. Their feathers were once highly prized, but today these magnificent birds are protected throughout their range. They are especially revered in Japan, where they are known as O-washi.

この写真は羅臼港から出港する観光船(ゴジラ岩観光)から撮影したものです。2日にわたり撮影し、1日目は8時半からの便で天気は小雪が舞う程度。2日目は5時の便で晴れていたが、流氷が厚く出向が6時半になり、朝日に浴びるオオワシは撮影できませんでした。
Steller's Sea-Eagle with drift ice in RAUSU Bay
These photos were taken from the tourist boat (GOJIRAIWA Tourist) on drift ice. I tried to take photos during 2 days, 1st day was snowish day, and 2nd day was fine day. But on 2nd day the drift ice was very thick, so tourist boat could not leave until 6:30, and we could not take photos of eagle over the drift ice at sunrise.

観光船からの撮影のみでなく、羅臼では道路からもオオワシを観察することができます。しかし400mmぐらいのレンズがないといい写真は撮れないと思います。
We can take photos of eagles not only from the tourist ship, but from the road. But good shot needs to use over 400mm lens.
