About These Birds
Eurasian Eagle-Owl
世界最大のフクロウで、4km先まで届く鳴き声と鋭い視力を持つ。ユーラシア全域に生息する頂点捕食者。
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
