Bats are a species of the genus Myotis. Its scientific name is Myotis lucifugus. The word Myotis means mouse-eared bats. This bat is commonly found in North America. It is one of the most commonly used bat in Chiropterology – the study of bats.
These animals have a uniformly dark brown, glossy fur on the back and upper parts. The fur on the lower parts are pale grey in color. The wings are dark brown and typically have a wingspan of 22 – 27 cm. Ears are small and black. They have a rounded tragus, which is a small eminence in the outer ear pointing backwards. This helps in collecting sounds from the back of the head. It is key feature in bats and help in locating prey and finding their way in the darkness.
The skull of a bat doesn’t have a sagittal crest – the ridge along the upper middle of the skull found in most mammals and reptiles. It has a short rostrum and a forehead which has an upslope. The braincase if flattened and sub-circular when observed dorsally. It has 38 teeth which, including the molars are sharp. This is
Female bats are larger than the males. Adult bats are 6-10 cm long and weigh around 5 – 14 gm.
Compared to the long-legged bats, brown bats have shorter tibia and lesser amounts of ventral wing hair. They also don’t have the keel on the
They can fly at speeds as high as 35
The female bat gives birth to one offspring. The young one is able to fly and obtain food by the time it is three weeks old.
Bats live almost all throughout North America. They are mainly found in

Habitat and Roosting
Bats use three different kinds of roosts. They have a day roost and a night roost. They also have a hibernation roost. They use the day and night roosts during spring, summer
- Day roosts are in buildings, trees, under rocks and in piles of wood. They are usually dark and provide good shelter. The day roosts are mostly exposed to the south-west. This will give them enough heat to make them wake up after sleep.
- The night roosts have closed in spaces. They also should have lots of bats to cluster together. This helps to keep them warm. Night roosts are usually away from the day roosts. The bats spend their time at night roosts immediately after they feed. This helps in keeping the feces away from the day roosts, thus preventing predators from locating them. Bats use the night roosters when temperatures are below 15-degree C. Hibernating roosts are usually in caves and unused mines.
- There is another type of
roostscalled the nursery roosts. These are warmer than the day roosts. These are mostly used by the females and young ones.
Bats are insectivorous. They feed on moths, wasps, beetles, gnats, mosquitoes, midges

There is, however, some truth in bats being dangerous to humans. Bats, unfortunately, are able to carry disease which can be transferred to humans. Some of these diseases can be dangerous and some of them are fatal. Because of the dangers that bats can impose, bat proofing to your home is very important.
There is a virus that was first identified in Australia that is fatal to humans and its transferral by bats. There are ongoing investigations into the Hendra virus. There is a link between the bats carrying the infection, the infection of horses and then the infection of humans. This virus can be fatal to humans and there is no known cure at the moment.
The Nipah virus was first identified in Malaysia and has been transferred to humans through their contact with pigs. The transmission of this virus through bats has been shown but they do not appear to transfer it directly to humans. Again, this virus is able to kill humans. Because of the dangers and disease that bats present, it is imperative that you have bats professionally removed from your attic.
Rabies and Bats
Bats are carriers of rabies. This is generally transferred through the saliva of an infected animal. This could occur through direct contact between a human and an infected bat. Unlike
Marburg hemorrhagic fever and the Ebola hemorrhagic fever are transferred by bats in Africa. Both of these can be fatal to humans and they continue to be a major health problem in regions of Africa.
There need to be sensible precautions taken with bats. Not all bats will be carrying diseases that will kill humans. Bats and humans have been coexisting relatively peacefully for thousands of years. But gaining a better understanding of the bats and how their relationship with disease and humans occurs will help ensure that this relationship is able to remain healthy.
