The brown long-eared bat, as the name suggests, is known for its unnaturally long ears. These ears are used to echolocate their prey, and of course, evade any oncoming predators. To locate prey, echolocation is used. This bat species uses frequencies between 27-56 kHz for echolocation. Unlike most bats, however, the long-eared may pursue their prey only by hearing. Their hearing is acute enough to detect a flying moth. Long-eared bats roost in trees that are near the ground. Appearance from roost sites normally happens in the dark, about an hour following sunset. Brown long-eared bats are found throughout Europe and are fairly abundant. This bat is found on the mainland of the United Kingdom, but not on Shetland, Orkney, or the Outer Hebrides Islands. This species of bat is not endemic.

The world is full of interesting living creatures, and we share much of our lives with them. The brown long-eared bat is only one of them, and there are several other unique creatures, like the black browed albatross and silver dollar, to learn about.

As males begin to cluster near hibernacula in late summer and early fall, breeding begins. Females retain sperm during hibernation until the spring after copulation. They return from hibernacula in the spring, ovulate, and the saved sperm fertilizes an egg. This method is known as delayed fertilization. Pregnant females travel to summer locations after fertilization, where they roost in tiny colonies to give birth to a single young one. At the start of the summer, maternal colonies of females and youngsters usually have 30-60 bats, while bigger maternity communities have been reported. By 18-21 days after giving birth, young bats can fly.

This species is a medium-sized bat with huge ears and has a noticeable fold on its back. Large-eared bats have 1.3-1.5 in (3.3–3.8 cm) long ears, nearly as long as their body, that easily differentiate them from many other bat species. In addition, they exhibit grayish-brown fur, a 9 in (22.8 cm) wingspan, and a total length of roughly 3.7 in (9.3 cm). As a result, brown long-eared bats are frequently confused with gray long-eared bats. However, gray long-eared bats are a Mediterranean species only seen in a few colonies in southern England.

These bats have a slow and low flight, flapping usually close to plants. Sweep glides and hovering are common. Even in limited spaces, the flight is extremely nimble. A juvenile brown long-eared bat's wings expand quicker than their body weight, changing their wing loading and their capacity to fly as they mature. Because of this allometric development, juveniles have grown more maneuverable and can glide more slowly at low power at 30 days. This is also when brown long-eared bats depart their roost for the first time.

The ability of the brown long-eared bat to optically recognize prey has been discovered in a study. On the other hand, visual cues were more essential than sonar cues, and the bats could not find prey using sonar cues solely. Brown long-eared bats feature huge ears and eyes. Therefore it's likely that passive listening and visual information help them find prey in crowded surroundings.
