why do bats hunt at night if they are blind?
442307
I'm quoting myself, for this question has been asked before.\n\nBats are not blind. \nWhat about phrasing the question the other way around? Bats don't have to fly at night because they're blind; rather they have evolved to occupy an ecological niche that involves crepuscular-nocturnal activity. Some bats took the evolutionary path towards small size and echolocation; those are the ones with small eyes and large ears. It's a matter of adaptation: they don't use their eyes as much as their sense of hearing, but usually structures or functions are not lost unless the _loss_ implies some benefit. Relatively small eyes are still functioning eyes!\n\nOther bats that are much bigger, have large eyes and good eyesight; the so-called flying foxes.\nAnd to return to the question: a good reason that bats fly during the night is that they encounter less competition from other animals for their food, which may be insects, flowers, fruits, fish, etc.\nCheck the Special Topics at the Animal Diversity Web: \nhttp://animaldiversity.ummz.umich.edu/site/accounts/information/Chiroptera.html

no\nthey are worse at night because you can't see them coming

Cockroaches are primarily nocturnal.  This is simply a mode of behaviour that evolved because it is more difficult to find prey visually in the dark - so cockroaches are less suceptible to predation in the dark.  They have evolved to respond to bright light by running and hiding in a darker location.

Excluding bats doesn't change the answer.  The answer is no.  Sight requires photons to hit specialized optic cells and generate a nerve signal.  No photons - no nerve signal.

The home range is determined by the availability of food, water and natural barriers. Say for example there were no other gorillas to limit the range of a family they would not go any farther than they had to to fulfill there requirements for living.  As for waking and sleeping it is dependent on the silver backs whims and his knowledge of the best time of day to do certain things such as feeding in a locale that might have predators early and late in the day but small risk during midday etc.

That effect is real and the explanation is very simple: it's our ears detecting tiny sound reflections from the surrounding environment. Around us there is always noise, although we may not perceive it consciously. But when our forehead is close to a reflecting surface, we perceive those tiny echoes, even if we are blindfolded.\nIt's a very rough version of what bats do all the time.

Why would you want to hunt out of a box?  Do you need a heater for when it's cold?  Want to bring in a tv and watch the game?  \n\nReal hunters don't hunt out of boxes or tent blinds.  If you need concealment, build a natural blind.

Some insects are attracted to light.  This is called phototaxis.  These insects that are attracted to light are usually nocturnal, active at night.  They use light sources for navigational purposes.  When light is more intense in one direction, they turn and move in that direction.  If the light source is somewhat enclosed, the insect may not be able to find its way out and therefore dies.

There are at least two theories (both unresolved).  Moths may be distracted from their navigation using moon light.  Or, moths try to avoid the light by seeking the darkness just beyond the light which is a confusing path.

I read once in a FATE magazine the ghosts generally  don't care much for noise, they will arrive when it is quiet.\nI have seen them during daylight hours or felt their presence.\nAnother theory is that they follow their "living" routine maybe your ghost is/was a night owl too.

They are actually increasing their range of vision by tilting their eyes toward the ground. Birds supposedly are extrasensory feelers, so they probably "sense" worms.

it gives them better night vision.

In most mammals, the pupil of the eye is round but in many of the flesh-\neaters such as the domestic cat, it becomes a vertical slit in bright \nsunlight and widens to cover most of the pupil in darkness. That is why \nthey see so well at night. In the eyes of the kangaroo and some hoofed \nanimals, notably the goat, the pupil is a horizontal slit. The eyes of \nmany animals shine at night because of a peculiar mirror, on the retina \nat the back of the eyeball, which reflects light; so that a cat's eyes have a \ngreen glare and those of alligators and crocodiles shine red. Such \neyeshine is found in many other kinds of animals including various \nmammals, sharks, sturgeons, and some moths, but not in birds nor \namphibians: and in all colors except violet and white.\n\nSwift animals, like the antelope, usually have large eyes. Nocturnal \nanimals like the deer mouse and flying squirrel, have also developed \nvery large eyes which enable them to see better and evade their many \nenemies. Others, which live mostly in tunnels, like the meadow mice, \nshrews and moles, have tiny weak eyes. Some, like the earthworm, are \nblind. Land snails have eyes on tentacles with which they can see \naround a corner, but leeches merely have "eye spots " or none at all. \nCrawfish and crabs have eyes on short stalks. Spiders have from 2 to 8 \neyes. Many insects have huge compound eyes -- the dragonfly has from \n20 to 25 thousand tiny lenses in a honeycomb pattern -- and some, like \nthe grasshopper, also have three little "simple" eyes for close vision. \nBirds have the keenest eyes and those of the hawks, eagles and vultures \ncan see small objects at incredible distances.

That sounds reasonable. Bats generally come out of the caves at night and they are pollinators. The scented nectar may attract them. If not bats, other nocturnal pollinators will be attracted.

Hmmm...not sure if a decoy of an owl perched outside your window would work or those stick-on silouttes of predators, such as hawks. Those work for smaller birds to keep them from banging into the windows...\n\nAre they purposely "attacking" or just hitting it becuz of the reflection they see?\n\nSleep in a different room? (just kidding)

because it gets dark at night on this planet

Bats or rats; better find out.\n\nPS Clicking is how their radar works, but we are speaking of vocalizations, not radar ( echolocation, to be precise ), and bats do vocalize.
