Inexperienced hand-reared motmots avoided a pattern of red and yellow rings but readily attacked a pattern of green and blue rings and also one of red and yellow stripes. The motmots' avoidance of the "coral snake%" pattern indicates that mimic snake species can derive protection from some potential predators.
经验不足的人工饲养卷尾蜂鸟避免了红色和黄色圆环的图案,但很容易攻击绿色和蓝色圆环以及红色和黄色条纹的图案。卷尾蜂鸟对“珊瑚蛇”图案的回避表明,拟态蛇类可以从一些潜在的捕食者那里获得保护。
