Mexican Free-Tailed Bat Size report

The free-tailed bat is a small bat suborder Canisnis batida, or mastiff bat. They live in groups, and some species, such as the Mexican free-tailed bat (scientific name: Tadarida brasiliensis), form large groups of millions of individuals. Mexican free-tailed bats (Tadarida brasiliensis) likely migrated from the southwestern United States and northern Mexico to southern Mexico to spend the winter in Cueva San Francisco (CSF), their southernmost habitat. Free-tailed bats do not hibernate, but some species are inactive in winter, and others are seasonally migratory.

Native to North and South America, the Mexican free-tailed bats fly fast, feed on insects, and inhabit tree cavities, caves, and buildings. They live together in colonies of up to hundreds of thousands and eat millions of pounds of insects each year.

The Mexican free-tailed bat is one of nature's most important and fascinating animals. It weighs less than half an ounce and is abundant in warm-blooded colonies. Population size is important for bat survival. This post introduces more interesting facts about Mexican free-tailed bats.

Mexican Free-Tailed Bat Size And Appearance

Mexican free-tailed bat has a dog-like face, short body, slender wings, small eyes, big nose, and big ears. The whole body has short black hair. Also known as guano bats, these enigmatic cave dwellers are capable of swift flights over long distances. The Mexican free-tailed bat is the fastest sustained flight in the animal kingdom, flying up to 100 miles per hour. Their top speed is 161 kilometers per hour. The most surprising thing is that they do not borrow the wind or dive to maintain their speed but rely on the strength of their wings.

Average Size of Mexican Free-Tailed Bat

The Mexican free-tailed bat has a wingspan of about 40 cm, a tail length of about 3 cm, and a weight of about 20 grams. It is considered a medium-sized bat. In the wild, the life span of Mexican free-tailed bats can reach 20-30 years, with an average life span of 37 years.

Living Habits

The number of free-tailed bats in Mexico is very large. About 15 million to 20 million live in Bracken Cave, and several other caves also have millions of free-tailed bats. These bats feed on insects, and they hunt in groups at night. They rely on sound waves to prey; high-frequency sound waves are their ideal weapons. The frequency of most bat calls is between 20 and 60 kHz, and the sound waves of these frequencies are difficult for predatory insects to perceive. In addition, they can fly freely and catch food accurately at night or in very dark environments.

Reproduction

Female free-tailed bats give birth to one offspring per year. Within an hour after Babao was born, the umbilical cord was still connected to the mother, and the mother and the mother used this time to get familiar with each other's smell and voice and instinctively used their limbs to cling to the cave wall. In the fifth week after birth, he began to practice flying, which was also the first time to test the ability of sonic positioning. The mortality rate of babies is very high; about half will die before one year old.

Final Words

Each year, free-tailed bats fly south and then enter Mexico and Central America for the winter; they return to northern Mexico and the southwestern United States in the spring. Despite the massive population of this bat, its numbers have declined at an alarming rate over the past 20 years. There is no reason to be afraid of Mexican Free-Tailed Bats. Thanks to their superior navigational abilities, they can fly around you instead of touching you. But no one should be picking up a bat from the ground. Like any wild animal, the Mexican Free-Tailed Bat will bite in self-defense. Bats pose little threat to humans who do not threaten them.
