虎頭海鵰 / Steller's Sea Eagle

虎頭海鵰是日本可看到的最大猛禽類。雄性體長約90公分，雌性體長約1公尺，如果張開雙翼的話，寬度可達2.5公尺。因為是越冬的侯鳥，會飛到日本北海道來過冬。整體的顏色呈現茶色，只有翅膀和尾巴是白色的。多會停留在流冰上或是降落到雪原上。在賞野鳥愛好家當中也很熱門。日本在1970年時指定為天然紀念物。

The Steller's Sea Eagle is the biggest raptor in Japan, with a length from head to tail of about 90 centimeters for male, and about 100 centimeters for female. In addition, they have a wingspan of about 250 centimeters. Being a migratory bird, they are only seen in Hokkaido in instances of resting on ice floes in the sea or snow fields on the land. Their bodies are predominantly brown, but a part of each wing and their tails are white. Birdwatching enthusiasts like to spot them, and they are popular as the subject of photos. In 1970, they were designated as a natural treasure of Japan.
