Why do sparrows often stumble on the ground, and swallows rarely go down to the ground to compete wi

This is what Darwin said, that natural selection has shaped thousands of life forms, as well as birds, and it can be speculated that in the past, the common ancestors of swallows and sparrows had pounced on some easily pounced insects. Over time, they mutate, with some birds becoming more agile and adept at catching insects in flight, while others have hard beaks that allow them to slice through seeds. When the number of insects that are easy to catch decreases, those birds that do not mutate are prone to starvation and eventually extinction, and the birds that become sensitive can continue to live by preying on insects in flight; Birds with hard beaks can continue to live by eating seeds.

So the two parted ways, and gradually became today's swallows and sparrows, and continued the habits of life throughout the ages, so swallows still catch insects in the air, while sparrows peck rice on the ground.

The sparrow is a resident bird, it is nicknamed the old thief, can not fly far, can jump on land, and specializes in some dirty work of stealing rice and rice, they are the best among birds.

The main food is different, sparrows are omnivorous, and they mainly eat ground food. So when they go to the ground, swallows are mainly insects and can hunt in the air.

Because the swallows' homes are on the beams of the houses, they have their own food in the nests, but the sparrows need to go down to the fields and grab the grain from the animals.

Sparrows are resident birds, omnivorous birds, cereal-eating insects, etc. Swallows are migratory birds, which go to the south to forage in winter and breed in the north in summer, and eat mainly insects and no food.

Because sparrows are more agile, they will fly away immediately when someone approaches, but swallows are different, swallows are clumsy, and if someone approaches, the swallows will not react and will be caught.

Swallows are migratory birds, they are agile and light, they can directly ingest flying insects in the air, they are the F22 of birds, and they do not need to go to the ground to feed.

Because swallows usually catch insects to eat when they are outside, they will also store some food in their nests. And sparrows will only pick up food on the ground to eat.

The sparrow's house is not in the house, but in the mountains, when they see people, they are strange, so they naturally go down to the ground and approach, and the swallow is not strange to people.

Sparrows are omnivorous birds that eat grains and insects, while swallows only eat insects, so they rarely go to the ground and grab grains with poultry.

Sparrows are gregarious. The life of group activity. Swallows are solitary beings. Each has its own advantages.

The pigeon does not eat the panting, and the swallow does not eat the ground.

As the saying goes: swallows don't eat what falls to the ground.

This question is not wrong, I am a rural person, now it is true that swallows are much less than before, especially to the Mid-Autumn Festival, this season, swallows are flying all over the sky, now look at the sky, really do not see swallows, I think the main reason is that the countryside is a brick house, it may be difficult for swallows to build nests, and the second is that it is possible to kill the swallows to death, because they need soil to build nests, and now the medicine in the rural fields is in the countryside, maybe the swallows are killed by the medicine when they build a nest in the mud, and there is a possibility, spring, Swallows fly from the south to the north, and swallows fly south in autumn, and in the process of flying back and forth, there may be sudden weather changes, such as typhoons, heavy rains, and swallow the swallows, because the swallows must pass through the sea when they go home, and they also have a rest when they fly halfway, and the resting place may be on the islands and reefs, which may bring them danger, and I analyze the reason for the lack of swallows is this situation.

Now there are indeed many sparrows, when they find that there are many sparrows, there are mainly two seasons, autumn and spring, they fly around in flocks in the tun, fall on the trees to play, the main reason is that the tiled houses in the countryside have created convenience for them, because there are gaps in the net room, they drill into the nest to build nests, reproduce, and now people no longer catch sparrows to eat, because sparrows are also protected by law, so people do not dare to catch sparrows to eat, so there are more sparrows.

Although I am a post-70s generation, I can sing when I am only a little older, a little swallow, and wear floral clothes. The song. The reason is that the elderly in rural areas can sing it and pass it on from generation to generation.

But I don't know if today's children will sing this song.

From this song, it can be seen that the little swallow is beautiful, and many people in the countryside like it.

So why are there fewer swallows and more sparrows in the countryside now?

When I was a child, the hundred-year-old banbi house in my hometown had swallow nests. At that time, there was no electric light in the countryside, so I insisted on asking my grandmother to build a ladder and let me go up and have a look.

Grandma confessed, only allowed to see but not to move. Good.

Putting on the pony lantern, I saw two little swallows, close to each other, their eyes wide, and they looked at me, and they didn't seem to be afraid.

Grandma, they're so well-behaved, so well-behaved.

Okay, you come down!

Child, you are not allowed to poke the swallow's nest, then the swallow's father and mother will be sad. Well!

Oh! It turns out that the swallow is a husband and wife, and if the other party dies, the other party may also die of hunger strike. Sparrows are different, flash marriages and flash divorces, and are unfaithful to love.

They reproduce (give birth) differently. Swallows have two nests a year, and they have to work hard, because they have to prepare to fly south in winter. The sparrow, on the other hand, has three seasons a year to breed, and it is also possible to breed if the weather is warm in winter.

Of course, this situation is relatively rare, hehehe!

Swallows basically only eat flying insects in the air, so they rarely go to the ground. If it's not on the ground, it will starve to death.

The sparrow eats more grain, and the insects on the ground will starve to death if they are not on the ground.

For the food of the sparrows is on the ground, and they shall eat.

For the sparrows are to eat grain, and the swallow's food is not on the ground.

Swallows eat small flying insects in the air, and they will starve to death on the ground, and sparrows will eat more grains, and small insects on the ground, if they are not on the ground, they will starve to death.

The toes are different, the hind toes of the swallow are very short, it is not easy to take off on flat ground, and there must be a certain slope before taking off.

Swallows basically only eat flying insects in the air, so they rarely go to the ground.

Sparrows feed mainly on the ground, so they often bounce around on the ground.

Because swallows and sparrows are not the same size, swallows are streamlined and can reduce drag during flight, while sparrows are also fatter, so when they fly, they have more resistance and fly slower.

The reason why swallows are more flexible than sparrows is mainly due to the shape of the swallows, which belong to the streamlined body and have less air resistance when flying, while sparrows have a round body and have more air resistance when flying.

Because the swallow has large wings and a streamlined body, it reduces the drag of flying in the air.

The body structure of the swallow is particularly suitable for flying, the swallow has slender and broad wings, and its feet are very short, and it can barely jump or walk, but can only fly.

First of all, it is necessary to understand the reasons why sparrows occupy swallow's nests. Often, this is because the swallows have left their nest or have not returned. If it is the former, then the sparrow will naturally leave when the swallow returns; If it's the latter, there are a few things you can try to lure the swallows back.

1.Clean up the nest: Clean up the garbage and debris left by the sparrows and wipe the inside of the nest with disinfectant water to ensure environmental hygiene.

4.Install protective nets: Installing protective nets can effectively prevent sparrows from entering the inside of the nest again. However, care should be taken not to affect normal activities and imports and exports.

In conclusion, this situation should be handled in a gentle manner and not to harm the sparrows and swallows. If none of the above chakra methods work, consider seeking professional help.

The sparrow grabbed the swallow's nest and there was a small young finch, and there was too much grass in it to clean up, so could it be poked?

Dear, if you poke a sparrow to grab the grass in the swallow's nest, it may cause panic among the sparrows and young finches, who may panic and want to flee from the nest or get hurt. Sparrows and young finches may be forced to leave the nest or have to leave the chicks if harassed repeatedly, which can take a toll on their survival and reproduction. Therefore, I recommend that you consider the safety of sparrows and chicks, as well as their importance in the ecosystem, before you act.

If you really need help burying branches, it's a good idea to consult with some professionals or conservation organizations and try safer and scientifically argued methods to protect sparrows and chicks.
