About These Birds
Atlantic Puffin
「海のピエロ」とも呼ばれるニシツノメドリは、北海の崖に穴を掘って営巣する魅力的な海鳥。口蓋に後ろ向きの棘があるため、一度に12匹もの魚を横向きにくわえて運ぶことができる。気候変動と乱獲による餌不足が脅威となり、個体数が減少している。
Thick-billed Murre
Thick-billed Murre (Brünnich's Guillemot), 39–43 cm, breeds in enormous cliff colonies across the Arctic from Newfoundland to Siberia. Thicker, shorter bill with white gape line. Dives to 200+ m — deepest diver among alcids. Piscivore; takes capelin, cod. Vulnerable to climate change in the High Arctic.
