What are the characteristics of owls?

1, the feathers around the owl's eyes are radial, and the fine feathers are arranged to form a face plate, which looks like a cat, hence the name owl. Its feathers are mostly brown, scattered with fine spots, thick and soft, and silent when flying.

2. Female owls are usually bigger than males. The head is large and wide, the mouth is short, the side is flat and firm, the top is hooked, the mouth base has no wax film, and it is mostly covered by hard feathers. Like many carnivores, owls have eyes in front of their faces, which makes them have excellent depth perception during hunting, especially in dim light.

3. Owls are mostly Nocturnal Animals, which lurks during the day and comes out at night. It is not easy to see them in the caves or eaves of trees during the day, but some species, such as spotted snipe, striped owl and carved owl, are restless and lonely during the day and often go out for activities; Species that have been active at night, once active during the day, tend to fly around like drunkards.

The owl's food is mainly mice, but also insects, birds, lizards, fish and other animals. They all have the habit of spitting "food pills" and have digestive ability. Food is often swallowed whole. The indigestible bones, feathers, hair, chitin and other residues in food are integrated into small balls and spit out through the esophagus and mouth, which is called food pills, also called saliva.

The big eyes are fixed in the owl's eye socket, so they can't turn at all, so they have to keep turning its head. Fortunately, they also have a flexible neck so that their faces can turn back. Due to the special cervical structure, the range of motion of their heads is 270. The left and right ears are asymmetrical, the left ear canal is obviously wider than the right ear canal, and the eardrum of the left ear is developed. Most of them also have clusters of ear feathers, forming auricles similar to humans. The auditory nerve is well developed.
