About These Birds
Common Myna
ハッカチョウ（Acridotheres tristis）— 南アジア原産で世界各地に移入された強い適応力をもつムクドリ科の鳥。黄色い嘴と目の周りの黄色い皮膚が特徴。
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.
