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)「🐮🧠 C’mon down to the Kids’ Farm and meet our moo-velous cattle: Holstein Magnolia (a.k.a. Maggie) and Hereford Willow! These sweet and charming cows are also incredibly intelligent—they have learned medical behaviors that enable our animal care team to closely monitor their health. In this Q+A, keeper Nikki Maticic shares some udderly fascinating training techniques! ✏️STORY: https://s.si.edu/43nT2bJ. (Link in bio.) . . . Photo 1: During a training session, Hereford Willow sticks out her tongue to touch a "target" (a tennis ball on the end of a dowel). Willow follows the "target" into a chute, which enables keepers and veterinarians to safely perform checkups. Photo 2: Holstein Maggie touches her nose to the target. Keeper Nikki Maticic reinforces this behavior by offering Maggie her favorite treat: hay cubes!」7月13日 6時23分
