About These Birds
European Roller
파랑새롤러는 비행 중 구르고 굴러다니는 화려한 공중 묘기에서 이름을 얻었다. 수컷은 번식기에 이 공중 묘기로 암컷을 유혹한다. 밝은 파란색과 밤색이 눈에 띈다.
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.
