All owls have ears.
Yes, owls have small ears located behind the eyes and covered by a tuft of feathers.
They have ears :]
to cut their ears
maybe , because they have big eyes so they would have small ears you might as well ask why is the sky blue? owls have great eye sight they do not need perfect ears as well.
There is not much room left for the owls brain, as the eyes and ears take most of the space in the owls head up.
Owls have exceptionally developed ears, there being three found types of ears in owls, most owls ears are placed asymmetrically which means whilst the ears are on the side of the owls head, just behind the facial disc, one side is higher than the other, allowing the owl to pinpoint sound height accurately as well as distance accurately.
Yes they are simply small
No. Some species of owl have feathery tufts that are sometimes mistaken for ears. Barn owls do not have these.
I believe that they were first called "long-eared owls" when people saw their ears.
the ears and eyes are really adapted to hunting
Their ears are holes on the sides of their head. Many owl species also have ear tufts on top of their head, but these are not their actual ears.
