Chapter 251
"Then let's not leave for the time being, and wait here to see what happens next." After all, we also want to know why.
"Okay, that's it!"
After Qi Tian exchanged his skills, he saw that the grbils were overwhelming, and there was a chill.
He silently shouted: "System, summon owls." "
Soon, some of the feathers around the eyes were radial, and the arrangement of fine feathers formed a face disc, and the face resembled ... The cat animal flew over. ......？
Its plumage is mostly brown, scattered with fine spots, dense and fluffy, and silent when flying.
This is the owl.
Qi Tian's latest skill is to summon these things to eat gerbils.
In the live broadcast room, the moment I saw the owl, I was immediately excited, and began to discuss one by one:
"About the owl, I know best, the female of the owl... Birds are generally larger than males. The head is large and broad, the mouth is short, the side is flattened and strong, the apex is hooked, the base of the mouth is not waxy, and it is mostly covered by hard feathers.
"Yes, like many carnivores, owls' eyes are located directly in front of their faces, which gives them excellent depth perception during hunting, especially in dimly lit environments." Interestingly, the big eyes are fixed in the owl's eye socket and cannot be rotated at all, so the owl has to keep turning its head.
"You know a lot, better than me!" All I know is that they also have a flexible neck that allows the face to turn backwards, and the head has a range of motion of 270° due to the special structure of the cervical spine. Also, their left and right ears are asymmetrical, the left ear canal is significantly wider than the right ear canal, and the left ear has a well-developed eardrum. Most also have a tuft of ear feathers that form a human-like pinna.
"Does anyone know that owls have well-developed auditory nerves." A barn owl weighing only 300 grams has about 95,000 auditory nerve cells, while a crow weighing about 600 grams has only 27,000! Qi
Tian is no stranger to these owls, he grew up in the countryside when he was a child, but later came to the city with his parents to do business, so he stayed away from the countryside.
However, many of the country animals there, he knew well.
For example, the owl, this is his most proud playmate in his childhood.
Owls belong to the birds of this order, which vary in size, from large ones such as eagle owls up to 90 cm in length to small ones such as oriental horned owls less than 20 cm in length.
The head is broad , the beak is short and stout and the tip is hooked.
The large binocular with respect to the head is common to birds of this order and distinguishes them from other birds, and the feathers on the front of the head are arranged in a faceplate, and some species have ear-like feathers.
The distribution of the two eyes, the face plate and the ear feathers make the head of the bird of this order very similar to that of a cat, so the bird of this order is commonly known as an owl.
The ear holes of this order birds are located on both sides of the head and are asymmetrical in distribution and shape, which allows them to pinpoint the source of sound in the dark.
The pupils of birds of this order are very large, making light easy to enter the eyes, and the rod cells in the retina (only one visual pigment, that is, rhodopsin can distinguish light and dark, can not distinguish details and colors) are very rich, but do not contain cones (which will be activated under strong light stimulation, there are three visual pigments, which can distinguish details and colors), so that the eyes are cylindrical (not globular), and have good sensitivity to weak light, suitable for nocturnal activities.
At first, dozens of owls flew in, then hundreds, and slowly became thousands.
Qi Tian knows that when the system summons, there will be thousands of owls, flying from far away.
For example, Changbai Mountain, Dabie Mountain, Tongbai Mountain, Tianmu Mountain, Qinling Mountain.
The owls here are the most numerous and also the most robust.
Because the columnar eyeball is supported by a hard scleral ring, the eyes cannot move in different directions, and the entire head needs to be rotated to look in different directions.
Therefore, the bird has a flexible neck bone and the neck can rotate 270 degrees.
In addition, there are 3 eyelids in the eye, the upper eyelid is lowered when blinking, the lower eyelid is covered when sleeping, and the middle eyelid is a linear tissue that moves up and down the eye surface to clean the eye surface.
Unlike other birds, the eyes are forward, and the field of view overlaps, so the distance can be distinguished.
Birds of this order have different wing shapes, generally short and round, 11 primary flight feathers, missing a fifth secondary flight feather, short and rounded tail, 12 tail feathers, and 10 in some species.
The birds of this order have strong legs, strong claws and inward curves, and some species, such as eagle owls, have feathers on the entire foot, and their appearance is extremely strong.
The toes of birds in this order are all toe turning, that is, the fourth toe can rotate back and forth.
The whole body of the birds of this order has soft and relaxed feathers, most of the plumage color is dull tan gray, the soft feathers have the effect of silence, so that the birds of this order fly quickly and quietly, plus the dull plumage, very suitable for nocturnal activities.
The visual acuity of the owl. In the dark of night, visibility is more than a hundred times higher than that of people. Unlike other birds, owls' eggs hatch one by one, and after the first egg is laid, they begin to hatch. Owls are thermostatic animals.
In some areas, there is a kind of owl, the eyes can emit light like a flashlight, and the brightness can be adjusted, the local indigenous people use owls to hunt, what is more amazing is that the light emitted by the owl's eyes is on the eyes of the animal, and the animal is unaware.
According to locals, the light from the owl's eyes can make the prey stand still. It is not known whether this is the case with owls elsewhere.
After these owls come, they are not polite to those gerbils, one bite at a time, very sweet!
In addition, when the gerbil saw the owl, his body was scared, let alone run.
Where to run!
One by one, they hid behind Qi Tian, or drilled into the sand holes.
At this moment, they were simply embarrassed.
Qi Tian did not sympathize at all, these gerbils should end up like this, after all, they would not do anything but eat food.
And who summoned them and let them besiege themselves?
It's also a big mystery.
If this person knows his location, why not personally bring someone to catch it, but let a group of gerbils run around?
Although Qi Tian stretched out his hand quite powerfully, it did not include catching mice with his bare hands.
The point is that he is afraid of the plague!
At this moment, Qi Tian turned into an indifferent god, holding two arms to admire, this owl, eating gerbils one by one, is quite good-looking!
Live room.
Fans were also surprised to see it, originally did not think that owls could come, after all, the entrance to the sand hole is very narrow, and these owls are relatively large, how can they enter?
Until later, these owls stood directly out of the sand and flew around in high spirits.
Fans find it strange, how did they do it?
