スミソニアン国立動物園さんのインスタグラム写真 - (スミソニアン国立動物園Instagram)「🥳🎂 On July 9, American Trail keepers celebrated Chipper’s 20th birthday! Our oldest North American beaver shared a healthy and delicious ice cake with his exhibit mate, Aspen. Keepers in the Department of Nutrition Sciences whipped up a wonderful treat made of frozen diluted apple juice with shredded greens and slices of apple, carrot and sweet potato comprising the colorful tiers. They topped it off with rodent chow “sprinkles” and corn on the cob “candles.” Join us in wishing him a happy birthday! . . . #NatZooZen」7月29日 4時26分
