鸟类的耳,因为没有人类的耳廓(哺乳动物叫耳壳),而且往往被羽毛掩盖,所以一般看不到。只有那些头部羽毛稀少的,像非洲鸵鸟、秃鹳、秃鹫之类,才能在它们两眼的后下方看到两个黑洞。其实那也不是耳廓,是外耳道向外的开口,相当于人的外耳孔。至于猫头鹰的耳状羽,跟耳毫无关系,只是样子像耳的一撮羽毛,所以叫耳簇羽。 Bird’s ear, because there is no human auricle (mammalian ear shell), and often covered by feathers, so generally can not see. Only those few feathered heads, like African ostriches, bald storks, vultures and the like, can see two black holes behind their two eyes. In fact, it is not auricle, is the opening of the external auditory canal, the equivalent of human ear hole. As for the owl’s ear plume, nothing to do with the ears, just like a pinch of plume of ears, so called ear plume.
