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)「🥳🎂 Happy birthday, Wiley! The younger of our two black-and-white ruffed lemurs turns 13 years old today. He is very outgoing and likes to be right in the middle of all the action. True to his name, Wiley is often the goof of the group. He can be a bit clumsy, sometimes, and tends to trip over his feet—but that just adds to his charm! . . . 🌳🙃 Black-and-white ruffed lemurs tend to stick to smaller groups of two-to-five individuals. Occasionally, groups of up to 16 individuals have been seen when food is readily available. Aloke and Wiley can be seen in the treetops of Lemur Island, and their booming calls can be heard around the Zoo! . . . Photo: Wiley hangs out at Lemur Island!」5月4日 23時00分
