About These Birds
American Robin
北米全域に分布し、春の訪れを告げる鳥として知られるツグミ（体長23〜28cm）。オレンジ色の腹と黒い頭部が特徴的。Turdus migratorius（アメリカコマツグミ）は北米最も親しまれた野鳥の一つで、芝生でミミズを引き抜く姿が日常風景として親しまれている。連邦政府と各州で厳重に保護されており、3州の州鳥に指定されている。Turdidae科。
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。
