Ear fox is a highly socialized animal. Parents and offspring form a family group of no more than 10, and live in underground caves. In order to adapt to the desert environment of high temperature and water shortage, they have a lot of necessary "equipment", and the functions of fur, ears and kidneys are all adapted to the desert environment of high temperature and water shortage.
The black-eared fox has a strong sense of territory. Each family controls a territory, and marks each family's territory with its excrement. Males will use urine as a sign, while females usually use feces to demarcate their territory, warning that "the fox is out".
Groups communicate through frequent screaming. Ear fox's voice is very loud, and it can emit many tones with different frequencies. Both adult foxes and young foxes make squeaks, whimpers or screams, and sometimes they roar.
As a master of digging holes, Erhu can dig a tunnel with a shovel-like claw, which is 9.75 meters long and the longest 10 meter. It can be called a "mansion". There are usually grass or bushes near the cave, and the ear fox will also use the branches of shrubs near the cave as support to prevent the cave from collapsing, and will also pick up the leaves of shrubs as bedding to make the "small home" more comfortable.
Generally speaking, each family member has his own independent "room", and each "room" has multiple emergency exits, which are disguised and difficult for even hunters to see through, so even if the enemy breaks into the house, most of them can escape calmly.
In an emergency in the desert, the ear fox is agile. It can dig a hole under the sand in 1 minute, and then dive in, into the vast sand sea, making it difficult for predators to find it.
The smallest canine, as a master of hole digging, can dig a hole in 1 minute, and the maximum length is 10 meter.
When hunting, you can turn your head left and right like a radar and find tiny sounds and vibrations in the sand to lock the enemy.
As an omnivore, the ear fox eats almost anything, especially bird eggs. According to Man and Nature, 90% of their food comes from insects and meat, and the rest 10% is the roots and fruits of plants.
Its meat menu includes small rodents, birds, eggs and reptiles. Vegetarian food is mainly fruits and plant seeds, sometimes fresh, and eat some leaves and plant roots.
Ear foxes sleep in caves during the day and feed at night to avoid the scorching heat of the desert sun. They rely on their senses, including hearing, to find food such as insects, birds and eggs.
When hunting, the ear fox stared at the sand surface and turned his head left and right like a radar to lock the enemy. Tiny sounds and vibrations in the sand can show them the location of their prey.
Once they find their prey, they chase after it. They are agile and can usually jump 0.7 meters high, which makes it easy for them to catch their prey.
In case they can't find drinking water, they don't worry. They eat leaves and roots of some plants, and they can get the water they need for survival from food.
