In addition to birds and airplanes, what else could be flying in the sky at night?????

I myself think that the most likely ones are meteors, moons, and an endless universe and small stars.

At night, drones, insects, bats, fireworks, monkeys fly in the sky, and if the wind is strong enough, waste paper and plastic bags may fly in the air.

Hello, the night leaves a good impression, there are planes flying in the sky from time to time, flashing lights, and whining sounds, spring and autumn ten, there are geese migrating from south to north, in addition to airplanes and birds, there is also a popular row at night, people fly kites with lights, and clearly visible satellites, all kinds of unknown insects, if you encounter a windy night, the sky may fly all kinds of garbage, like confetti, plastic bags and the like, of course, you also sometimes see the flying Kong Ming lanterns, festival flowers, in fact, at nightThere are many, many things flying in the sky, and if you look closely, there are too many.

In addition to birds, planes, bats may also fly in the sky at night. Bats are often seen at night and carry very high backs. So it could be a bat that flies at night. Of course, it may be mosquitoes flying in the sky at night. Mosquitoes are also often seen at night.

In addition to birds and airplanes, there are many satellites, flying clouds, meteors, and possibly flying insects ...... the sky at night.

Bat. Mosquito. Owl. Firefly. There are also countless nocturnal animals and insects.

In addition to birds and airplanes, there are many other things flying in the sky, such as bats, such as garbage, and stars that you see, or beetles and so on.

In addition to birds, white clouds, airplanes, kites, various insects such as butterflies and dragonflies, bats that come out at night, and drones fly in the sky. ：

Then, there should be the most flying insects!

UAVs, space stations, spaceships.

In addition to birds and airplanes in the sky at night, there may be. You write little bugs. That's all that is supposed to be it, right? And then there's a few more. I can't afford to say anything like that. It's because of these balloons that the wind blows in the sky.

Kong Ming lantern: It looks like a star from a distance, sometimes orange and sometimes white;

Glow-in-the-dark kite: characterized by moving in a small area in situ, the color is very beautiful;

Luminous airship: Slow flight speed, easy to mistake for UFO in rainy and foggy days.

In addition to birds and airplanes, there may also be aviation aircraft, meteors in the sky.

Bats, owls....Some animals come out at night.

It could be meteors, bullets, shells, UFOs, etc.

There are many species of flying insects, as well as various aerospace vehicles.

Of course, it's still UFO, and now the aliens are not vacant.

There are so many flying insects in the sky, for example, in nature, various flying insects, night bats make lanterns, satellites, and meteors.

There are also grasshoppers, butterflies and ...... that can fly

There may also be insects, and I think that's the most numerous!

It's also possible that the cowhide is flying, because the people below are blowing hard.

In such a situation, there may be flying sand and rocks, strong winds, and you are not sure what is flying!

The most annoying thing at night is the mosquitoes flying around.

Non-biological: airplanes, ***, jets, hot air balloons, hang gliders, parachutes.

Space: rockets, space shuttles, satellites, comets (meteors), stars.

Creatures: Dragonflies, butterflies, moths, greasy insects.

Bird migration is basically continuous day and night, and only rests for a short period of time in the middle. As a result, almost all migratory birds will have time to fly and migrate at night.

Birds basically do not have night vision, except for a few owls and falcons (such as owls.

Nighthawk, etc.). This is because most birds have cones in their eyeballs.

The main stem resolves color much more than rod cells (the main stem resolves the brightness and darkness of light), and in some diurnal birds there are even no rod cells in the eyeball, which means that in the case of low light, when the color difference of the object is not obvious, the visibility of the object to this type of bird is almost zero. Many birds that are migratory or can fly long distances are poleless birds, such as pigeons and geese.

Wait. Migratory birds do not have to have the ability to do so. Because a bird's vision is mainly related to its ability to hunt, but not to its ability to orient.

The migration of birds mainly relies on their orientation system, and the orientation system of birds is quite complex, with many sets of mechanisms, including star position, sun and moon position orientation method, magnetic field orientation method, air flow direction orientation method, etc. (see Tongyan Fairy upstairs for details), so the lack of night vision does not affect the continuous flight of birds at night.

But if you look closely, you can see that all birds that don't have rods (and I mean none at all) don't hunt at night to replenish their migrating strength. Therefore, the basis for judging whether a bird has night vision is not to observe whether the bird will fly at night, but to observe whether it will hunt at night.
