About These Birds
Anna's Hummingbird
안나 벌새는 북아메리카 서해안에 서식하는 중간 크기의 벌새입니다. 수컷은 화려한 핫핑크색의 목 깃털을 가지고 있으며, 꽃에서 꿀을 먹고 작은 곤충도 잡아먹습니다.
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.
