Batman got it wrong. Despite the famous idiom, bats aren’t blind. All bats rely on sight to find food, avoid predators and navigate to and from roosts. As expected in a nocturnal mammal, their eyes are heavily loaded with photoreceptor cells called rods, which maximise their ability to see in the dark.

But, unlike cats, opossums, owls or other night hunting creatures, they do not have excellent night vision. Since they are nocturnal or night dwellers, by nature, the use a “second sight” or built in sonar, to help them see in the dark. This second sight is called Echolocation.
Can bats see during the day?
Yes, most bats have perfectly normal vision and can see well enough during the day to fly around safely. They may well see better than us during the night though.
Why do bats hang upside down?
Because of their unique physical abilities, bats can safely roost in places where predators cannot get them. To sleep, bats hang themselves upside down in a cave or hollow tree, with their wings draped around their bodies like cloaks. They hang upside down to hibernate and even upon death.
How long does a bat live?
Although most bats live less than 20 years in the wild, scientists have documented six species that life more than 30 years. In 2006, a tiny bat from Siberia set the world record at 41 years . The Townsend’s big-eared bat’s average lifespan is 16 years. Photo by Ann Froschauer, USFWS.
Are bats 100% blind?
No, bats are not blind. Bats have small eyes with very sensitive vision, which helps them see in conditions we might consider pitch black. They don’t have the sharp and colorful vision humans have, but they don’t need that. Think of bat vision as similar to a dark-adapted Mr.
Do bats drink blood?
Only three of the more than 1,300 bat species in the world are vampire bats: the common (Desmodus rotundus), the white-winged (Diaemus youngi) and hairy-legged (Diphylla ecaudata) vampire bats. Residing in Central and South America, these are also the only bats who consume blood — and only blood — for food and water.
Are bats good for anything?
Bats can help control the populations of beetles, moths, and leafhoppers. Many insects can hear bats up to 100 feet away and will avoid those areas occupied by bats. Some people build bat boxes and post them on their houses or sheds. If bats occupy the boxes, insects are sure to be less plentiful around those places!
Can bats hurt you?
Bats and flying foxes may carry bacteria and viruses which can be harmful to humans but the risk of infection is low. People who are not trained and vaccinated should not handle bats. If you find an injured bat or flying fox, do not attempt to help the animal yourself or touch it in any way.
Do bats bite humans?
Bats do not bite unless they are provoked. Even the occasional rabid bat seldom becomes aggressive. However, since bats are a rabies vector species in most places and, like all wild animals, can bite to defend themselves, it is crucial to take all necessary precautions to avoid a potential exposure to the virus.
Do bats lay eggs?

What does it mean when a bat hisses?
Bats hiss and make screeching sounds as a defense mechanism if they feel threatened. And although the majority of bats can take flight from the ground a few species of bats have difficulties and people often mistake this behavior as being ill or rabid.
Are bats afraid of light?
Bats don’t like light. Although they don’t rely too much on their poor sight, they can see, and they prefer dark areas. This is why bats are notorious for roosting in caves. Because you lose a little light with each bend in a cave, you’ll often find them roosting deep within, but that’s only the case in nature.
