Kids’ Farm keepers say this charming cow is playful, affectionate and also has a mischievous side! . . . Maggie and Hereford Willow 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: Holstein Maggie touches her nose to the target. Keeper Nikki Maticic reinforces this behavior by offering Maggie her favorite treat: hay cubes!」9月17日 3時00分
