What does the animal rely on to identify the direction?

Here are the answers from other brothers, willing to help:

Dogs recognize their way by smell, and they urinate along the way to identify the path they have walked.

Ants rely on their antennae to recognize scents to judge the road, and when they travel, they will leave their own scents on the road they walk, so that they can pass by their peers. They can easily get lost if they are sabotaged in the path they have traveled.

Bats rely on a radar system that emits electromagnetic waves, and then reflects back the band to judge the road ahead.

Pigeons rely on geomagnetism to determine their direction. Scientists have discovered that pigeons have some magnetic substances (ferric tetroxide) in their brains.

The way of identifying the direction of various animals is different, which is related to their living environment, in the land is generally the eyes, ears and eyes, in the air in addition to the eyes and ears and rely on the geomagnetic field, such as pigeons. The creatures in the sea are so complex, and the animals that live in different depths of the water have different ways of recognizing them. In general, aquatic organisms and fish rely on the assembly lines on both sides of their bodies, and they can determine the direction by sensing the direction of the water flow.

How do animals find directions? Millions of king-spotted butterflies fly from the United States to the mountainous mountains of central Mexico every year to breed, and migratory birds that fly thousands of kilometers to find their way to their habitats, do they also have maps and compasses?

Oriental animals include: pigeons, bees, whales, various migratory fish and migratory birds, etc.

Animals can almost tell the direction of the lead height.

In fact, because they all have their own habitat, they will remember the road every time they go out.

Profile of the pigeon:

There are two categories: wild pigeons and domestic pigeons. There are two main types of wild pigeons: rock-dwelling and bush-excited arboreals. After long-term cultivation and screening, there are many kinds of food pigeons, play pigeons, racing pigeons, military pigeons and experimental pigeons.

In 3000 B.C., the fifth generation of the Egyptian dynasty had records of pigeon breeding. Chinese pigeon breeding also has a long history. According to the pigeon shed on the pottery carved house unearthed from the Han tomb in Lushan County, Sichuan, it is inferred that public opinion has been raising pigeons in 206 A.D. at the latest.

Today, all continents of the world have their own wild and domestic pigeons.

The classification of pigeons varies from person to person. According to Japan's "Encyclopedia of Animals", there are 5 populations of 250 species of pigeons on the earth; According to Japan's "Dictionary of All Things", there are as many as 550 species of birds in the dove family. From a large number of wild pigeons with different characteristics, to a variety of domestic pigeons, it shows that today's domestic pigeons are a product of multiple origins.

There are two main ways for animals to identify direction, one is to identify the direction by the sun (e.g., bees) and the other is to discern the direction by sensing the earth's magnetic field (e.g., pigeons).

1. The sun discerns direction: Bees and carrier pigeons use the sun as a compass to determine direction. The daily displacement of the Sun is a part of its flight data.

2. The magnetic field refers to the direction: turtles, whales, migratory birds, some fish and blind rats rely on the geomagnetic field to go south and north. Its "receiver" is a magnet, magnetite crystal, located inside the skull.

Like magnetic metal shavings, magnetic grains align themselves with the magnetic field, which signals the brain about direction. In addition, animals should be adapted to magnetic inclination, which can help them determine their precise position. Self-tracking of the Earth's day-night cycle of the body's internal clock.

Magnetic field refers to the field that transmits the magnetic force between physical objects, and it is a special substance that cannot be seen or touched. The magnetic field is not made up of atoms or molecules, but the magnetic field exists objectively, and it has the radiative properties of wave particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets do not need to be in contact at the physical level.

Common methods for distinguishing animals:

Look at physical features.

The specific physical characteristics are gathered on the head and body, the head is the eyes, nose, mouth, ears, and the body is the hair, limbs, tail, etc., these are the appearance of animals, and some animals can be distinguished by this.

Look at the habits.

Animals that look very different can be distinguished by their appearance, just like giant pandas and lions obviously look different, so this is very easy to distinguish. However, if you encounter animals that look very close, then distinguishing them requires the observation of habits. Just like a donkey and a mule, at first glance, the appearance of the two is not very different, but the sound of barking and some survival habits are very different, including what to eat, the water to drink, whether to have children, etc., these are the living habits that can distinguish the characteristics of animals.
