Chapter 252
Just when Qi Tian was directing the owl to eat gerbil, not far from the sand hole, there was a figure, gradually approaching
, he squatted down from time to time, lying on the desert, listening to something.
The squeaking sound from below the sand let him know that gerbils were in danger.
Because the usual gerbil's call is different from the current one.
Now it is clearly in danger.
This person is in a hurry, gerbil is all his brainchild, if something happens it really kills him.
He quickened his pace and ran in the direction of the sand hole, the direction where the gerbil's sound came from.
Because many people don't know much about it, someone sent out a barrage on the public screen of the live broadcast room to supplement knowledge:
"Owls mostly inhabit trees, and some species inhabit rocks and grass.
The vast majority of owls are nocturnal animals, lying in the day and nocturnal, hiding in the trees and caves or eaves during the day is not easy to see, but some species such as the spotted grebe, longitudinal-bellied owl and eagle owl are also restless and lonely during the day and often go out; The type of nocturnal travel, once active during the day, often flies bumpy and erratic like drunkenness.
The owl's diet is mainly rodents, but also insects, birds, lizards, fish and other animals.
They all have the habit of spitting out "food pills", and their vegetarian muzzles have digestive ability, food is often swallowed whole, and the indigestible bones, feathers, hair, chitin and other residues in the food into lumps, forming small balls through the esophagus and mouth spit out, called food pills, also called saliva. Scientists can understand the food properties of food pills based on their analysis.
Once the owl determines the direction of its prey, it quickly strikes.
The owl's feathers are very soft, and the wing feathers have velvety dense down, so the frequency of sound waves generated by the owl when flying is less than 1 kilohertz, and the general mammalian ear does not feel such a low frequency. Such a silent sortie makes the owl's attack more "blitzkrieg" effect.
According to research, when an owl is pounced on its prey, its hearing still plays a role in localization. It can constantly adjust the direction of the fight according to the sound generated by the prey when moving, and finally the claw is released, which is effective in one fell swoop.
Owls are color blind and the only birds that cannot distinguish colors, except for some birds that are used to nightlife, such as owls, etc., because there are no cone cells in the retina to distinguish colors, many birds have color perception.
Crows need to find a place to land when flying high, and the color will help them judge the distance and shape, so that they can catch the flying bugs and land gently on the branches.
The birds' ability to discriminate colors also facilitates their search for mates. Imagine that male birds often use their colorful feathers to attract the opposite sex, and if they can't feel the color, what is the charm of male birds?"
After the fans saw this, they woke up like a dream, it turns out that there is such a big knowledge here!
Just as they were being mourned, some small pointed heads came out of the sand holes.
These things are a little bigger than the owls before them.
This is an eagle owl!
This is a nocturnal raptor!
How could it be here!
"Body length 22-32 cm, weight 212-230 grams. There is no obvious face plate and collar, and the eyes are black whiskers. Migration. The eyes are large, dark, and hawk-like, hence the name. The beak is strong and hooked. The wax film at the base of the mouth is covered by hard whiskers. The shape of the wings varies, and the fifth secondary flight feathers are missing. The tail is short and rounded with 12 tail feathers. The feet are strong and powerful, often all feathers, and the fourth toe can be reversed backwards to facilitate climbing. The claws are large and sharp. The tail fat glands are exposed. No secondary feathers. The periphery of the ear hole has ear feathers, which help distinguish between sound and night localization at night.
"It inhabits montane broadleaf forests, likes to be active at night and at dusk, flies quickly and silently, and preys on insects, mice and small birds. Nests are found in tree holes or rock crevices. "
Eagle owls are medium-sized birds of prey. Because of its eagle-like shape, hence the name, this body shape also allows it to move during the day. In keeping with this habit, it also does not have prominent plates, collars, and ear feather tufts that are mainly used to collect sound waves. The upperparts are dark tan. The forehead is white, with white spots on the shoulders, and the throat and front of the neck are yellow with brown stripes. The rest of the underparts are white with teardrop-shaped reddish-brown spots and black transverse and terminal spots on the tail feathers.
"Iris yellow, mouth grey-black, mouth tip black-brown, tarsal tepal feathers, naked toes, flesh red, with sparse light yellow bristles, claws black. It often inhabits mixed coniferous and broadleaf forests and broadleaf forests below 2000 m above sea level, especially in forest valleys, and on tall trees in groves, forest edge shrubland, orchards and agricultural areas in low hills and foothill plains. "
Eagle owls mostly roost in the canopy during the day, active at dusk and at night, and sometimes during the day. Except for pairs during the breeding season, most of the other seasons are solitary, and the chicks are mostly in familial groups after leaving the nest and during migration. The flight is fast and agile, and there is no sound. Fly faster and more powerful when attacking intruders. Often flies out of the perch suddenly. "
The breeding season often chirps at dusk and at night, and often repeats the chirping. The call is rounded, the ascending false voice whistle pung-ok, the second tone is short and high-pitched, repeated every second or two, the sound is variable, sometimes making a short and muffled call of "bouncing, bouncing, bouncing", sometimes lasting a long time, usually in the morning and dusk.
It feeds mainly on rodents, small birds and insects. Hunting prey sometimes breaks into residents' homes.
In northern China, it is a summer migratory bird and in the south it is a resident bird. Active, active in the forest edge before dusk, flying in pursuit of insects in the air. Sometimes families forage together around glades.
Qi Tian explained to everyone while watching for a long time, because these things were more fierce than the previous owls, and they lived farther away.
I don't know how, but I actually summoned these things.
Qi Tian can't cry or laugh, is it so good?
In this case, should he rejoice, or should he cry?
These eagle owls surrounded the gerbils, and those that the owls did not catch just now, or those that had already burrowed into the sand, were caught by the eagle owls.
Its sharp claws, like pincers, no gerbil can escape.
After a short time, the sand caves became gerbils.
In the beginning, owls and eagle owls will swallow gerbils into their stomachs, and as a result, one by one, the belly is scary.
Therefore, they dare not eat more, and they suffer more if they eat more.
It is absolutely good for us to be able to eliminate gerbils, but for him, it cannot be digested and stored,...... This one and that one is simply overwhelmed!
