About These Birds
Common Kestrel
황조롱이는 유럽에서 가장 흔한 매로, 날아오르며 정지 비행하는 능력으로 유명하다. 적갈색 등과 뾰족한 날개를 가지며 고속도로 옆과 도심 지역을 포함한 다양한 서식지에서 볼 수 있다.
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.
