Habitat Comparison

A rapid, twittering song: a long stream of 'vit-vit-vit' and rolling chirps. Also gives a sharp 'vit' flight call. Song can last many minutes without pause. Musical and liquid.

南アフリカ西部沿岸とその島嶼に生息するペンギン（体長60〜70cm）。黒い背中と白い腹に黒い縦縞、眼上部のピンクの皮膚が特徴的。Spheniscus demersus（アフリカペンギン）はロバのような「ブレイヤー」という鳴き声から「ジャッカスペンギン」とも呼ばれる。過去1世紀で個体数が97%以上減少し、絶滅危惧種に指定されている。Spheniscidae科。
Barn Swallow
ツバメは世界で最も広く分布するツバメ科の種で、スズメ目の中でも最長の渡りを行うもののひとつ。北半球全体にわたってその到来が春の訪れを告げ、古代ギリシャから現代の詩に至るまで文化的な言及を生んできた。ツバメは営巣にほぼ完全に人工構造物を利用するようになっている。
