Why do you rarely see sparrow carcasses nowadays?

The sparrows outside the window, how come you rarely see their carcasses?

Sparrows are a very common bird and can be found everywhere.

The sparrows on the roadside

The same large number of rats, people often see dead rats, however, so many sparrows, people rarely see it after death.

Is it that sparrows have the art of dissipating the body, not leaving a corpse after death? Or is it that the sparrow flew over, it is bound to leave traces.

The little bird around

The sparrows we can see everywhere, in fact, there are 27 species, they all belong to the finch family Sparrow genus, distributed around the world.

We can say that, except for Antarctica and some islands, sparrows are everywhere.

Sparrows are small, with a body length of about 15 cm and a weight of only 30 to 50 grams, which means that a larger sparrow weighs only one or two, equivalent to the weight of an egg.

Such a small sparrow, but the voice is not small, otherwise how can it talk too much on the pole?

Sparrow taking off

As a resident bird, the sparrow basically does not migrate, it will always live in a certain area and pass from generation to generation.

Then the question arises, since sparrows are ancestral living area, why rarely see sparrows die?

At least live to see the birds, to see the corpse, sparrows will also be born old, sick and dead.

It is difficult to believe that the sparrow will be buried, the body of their companions buried?

Sparrow and lotus

The life expectancy of a bird is directly proportional to its size, the larger the size the longer the life expectancy.

The exception to this rule is the sparrow, which can live 5 to 10 years, which is still quite long compared to its size.

Only, the vast majority of sparrows have difficulty living to the end of their lives, so the average age of sparrows in the wild is in about 3 to 5 years.

There are actually multiple reasons why we have a hard time finding sparrow carcasses.

Why is it hard to find sparrow carcasses?

Sparrow carcasses are hard to see

Sparrows in the wild hardly live to old age, they die for various reasons, most often being eaten by other animals.

The sparrow is a lower level of the food chain, and all animals except plants and some insects can ride on their heads.

Its main natural predators are raptors, snakes and cats, and most sparrows die unnaturally and are eaten by their natural predators after death.

Raptors mainly catch sparrows in the trees to eat, it is difficult for people to find; snakes are more covert activities, also not easy to be found; may also be the case of cats catching sparrows will occasionally be found by people.

Therefore, the important reason for rarely seeing the sparrow carcass is that the sparrow is eaten.

Cat catching sparrow

Of course, another reason why sparrow carcasses are rarely seen is the color of sparrow feathers, which are difficult to spot.

Sparrows are black, white, gray, and hemp mixed colors, making their feathers extremely concealing in their natural environment.

After death, sparrows are hard to find by humans even right in the fuck grass.

Although there are many sparrows, but their size is very small, dropped on the ground plus some fallen leaves, weeds cover, almost no one will notice.

One more thing, do not underestimate the decomposers underground.

The sparrow's body is so small that it is not difficult for microorganisms on the ground to decompose a sparrow.

If the temperature is right, it only takes a day for the decomposers to partake of the sparrow's carcass.

Sparrows living in the city only account for a small percentage of the total number of sparrows, most of which live far from the population and are more dispersed.

There are only a few places for sparrows to stop in the city, and sparrows appear together to give the impression that there are a lot of sparrows in the city.

In reality, there are more sparrows in places far from the city, and no one will know that they are dead, much less see them.

Sparrows are more away from humans

The theoretical value of sparrows is 5 to 10 years, but in reality they can only live for 3 to 5 years, and some unfortunate sparrows even die in their nests.

The vast majority of sparrows die unnaturally and become food for their natural predators, so the carcasses are invisible.

The remaining sparrows that die by accident or disease are hard to find when they fall to the ground.

The decomposers on the ground are very active and may decompose the sparrow carcasses in a day's time.

Natural decomposers

The role of natural decomposers sparrows

The mortality rate of the sparrow is actually very high. It is a late adult bird, born with its eyes unopened, and requires 15 days of full parental feeding.

During this time, the young birds are in great danger of being parasitized by a variety of parasites, such as horse fly larvae.

They can also have their nests pulled out by animals that go up into the trees, such as cats, dryads (raccoons) and even monkeys.

Once this nest-emptying thing happens, the sparrow couple's hard work is wasted and they have to make another nest.

Monkeys pulling out birds' nests

But the power of the sparrow is that it can breed all year round.

Sparrows do not migrate, there is no fixed estrus period, all year round can be born, the abundance of food to determine a pair of sparrows a few times a year, generally speaking at least twice.

Sparrows are monogamous birds and will raise their young together; they are betting on a probability.

A nest of four to six sparrows is a "good man" as long as it survives 15 days.
