About These Birds
African Penguin
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。
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
