Bats

Feeding batfish can be problematic. Sadly, many never take to eating in captivity. Live prey works best, especially crustaceans. Eventually, a batfish may learn to take frozen shrimp or mycids. Small snails, worms, and feeder fish may also be offered.

First the flying fox says goodbye to his mommy. Then he puts on his coat and grabs his camo binoculars. Then, using a turkey mating call, summons the power of dogs all across the world. Fish jump into the foxes mouth. And THAT children, is how a flying fox finds its food.

Bats do build nest, do to scientist they really do build nests.

They aren't threatened as being a ghost you are quite transluscent and do have the ability to pass through solid objects. They're not threatened unless they're alive. They're not threatened because they're already ghosts and dead. They're not threatened according to Britanica's Encyclopedia. No thanks is needed, you're welcome.

Echolocation is useful because it helps bats, shrews, dolphins/whales etc. It has evolved to allow the animals to "see" around them in the night (bats) or in murky water (dolphins/whales) otherwise these animals would have died

bony fishes

some bats eat fruit or blood vampire bats eat blood and some bats eat bugs it really matters of what kind of bats eat

The offspring or young of the average Bat is called a "pup" usually.

The grey-headed flying fox is the largest bat in Australia. This flying fox has a dark-grey body with a light-grey head and a reddish-brown neck collar of fur. It is unique among bats of the genus Pteropus in that fur on the legs extends all the way to the ankle. Adults have an average wingspan up to 1 m (3.3 ft) and can weigh up to 1 kg (2.2 lb). The head and body length is between 230 and 289 mm (9.1 and 11.4 in), with an average of 253 mm (10.0 in). The forearm length is between 138 and 180 mm (5.4 and 7.1 in), with an average of 161 mm. Weight generally varies between 600 and 1,000 g (1.3 and 2.2 lb), with an average of 677 g (1.49 lb). It is tailless, with claws on its first and second digits. Since it does not echolocate, it lacks tragus or leaf ornamentation found in most species of Microchiroptera. It relies on sight to locate its food (nectar, pollen and native fruits) and thus has relatively large eyes for a bat.

Fruit and sometimes insects

Bats are nocturnal, which means they are active at night. They come out then to search for food, because it is cooler and less predators are around. They use echolocation to see in the dark. During the day, they catch up on sleep in tree hallows, stumps, and dark caves.

With their wings, if they can fly during the day there is no reason they cannot fly at night.

However, if you mean why can they fly in the dark without hitting things, it is because they use sonar to navigate.
The bat sends out a call and then listens for the echo, from the time between when it sent out the call to when the echo arrives it can work out how far away things are and so avoid them.

They sleep 6-8 hours a day.
they are one of the longest sleepers that are animal!!

An bat mammal can also be called a chiroptera.

Bats have a sort of 'sonar', which enables them to detect objects before flying into them. The sonar also helps them avoid flying into each other, as well as helping them find their food, which is largely mosquitoes.

They use their echo-location by sending a click sound that is too high-pitched for humans to hear. It bounces back when it hits trees or other obstacles, and the bat then gathers the information and creates a picture of obstacles and prey.

Bats, and birds like the Flycatcher.

Mostly night flying insects. Also crickets, moths, beetles, mosquitoes, and termites.

Bats predators are snakes, racoons, opossums. and tarantulas. Sometimes a hawk or a owl will snatch them from the sky.

Bats have babies in caves. After a few weeks, baby bats cling to their mothers while the moms hunt for food.

Fur on the body and a skin between the bones of the wings.

Hawks and owls prey upon fruit bats. So do domestic cats. Humans even sometimes kill them because they are not always something you want in your yard, although they do kill the mosquitoes and other undesirable insects.

They can but they are usually asleep in sheltered roosts such as inside hollow trees, buildings or caves during the day - with one or two exceptions, they are nocturnal animals. Odd question - I wonder where the belief you are questioning, arose

These are both types of flying animals. There are many different species of both bats and birds; there are insect eating and fruit eating examples of both.

there's no such thing of a flying fox

they are small and sometimes can be pests, many people are scared or just disgusted by their habits

Bats get a bad reputation in the movies (vampires). They are frequently carriers of rabies... or worse. Some live in great communities in tight, dark quarters (caves) that aren't suited for interaction with humans. They only venture forth from their caves in the first hours of evening darkness. They're not very sociable. The floors of their caves are frequently covered with a thick blanket of guano (bat feces). To add to the above, as a rule, many species are not very photogenic; they don't do closeups.
