猫头鹰看见你了吗(Owl be seeing you)
穴居猫头鹰有很多区别于它们聪明的表亲的地方。他们不在树上睡觉,而是在地上安家,经常接管地松鼠或土拨鼠遗弃的隧道。它们也是最小的猫头鹰物种之一,长约23厘米。与其他鸟类不同的是,它们通过发出卡嗒卡嗒和嘶嘶声来抵御捕食者,比如响尾蛇。这些猫头鹰在白天最活跃,其他猫头鹰都在打盹。
原文:
There's a lot about burrowing owls that distinguish them from their wise cousins. Instead of sleeping in trees, they make their homes in the ground, often taking over tunnels abandoned by ground squirrels or prairie dogs. They're also one of the smallest owl species, measuring about 23cm. Unlike other birds, they ward off predators by making rattling and hissing sounds, like rattlesnakes. And these owls are most active during the daytime, when other owls are snoozing.
