I found that my feathers changed due to the change of seasons.

The colorful costume used to attract females has now changed into a look suitable for flying.

Although he no longer looks good, he is now more suitable for flying.

At this time, the birds in the oasis flew up in droves,

Zhao Meng hesitated for a moment, then followed the flock of birds in one direction,

He didn't know what the winter was like here, but to be on the safe side he still embarked on the migration path.

"In the thirteenth week, during migration, you were chased by a predator, but you took advantage of the flock of birds and got rid of the predator!"

At this time, Zhao Meng was still flying in the sky,

Thinking back to the predators we encountered frequently during this period,

He suddenly thought of something,

When facing a predator, you don't need to be the fastest, you just need to run faster than other animals.

As a fringed snipe, Zhao Meng deeply understands this.

Note:

There are three male species of fringed snipe,

These three types of male birds have completely different behaviors during courtship.

The first type is an independent male bird, which obtains the right to mate through fighting.

The second type is the satellite male, which wanders around the territory of the independent male.

Taking advantage of the male bird's absence, he invades his territory and commits crimes.

The third type of female-like fringed sandpiper is also the strangest male bird.

This male bird disguises itself as a female, blends into the territory of the independent male bird, and mates with the independent male bird.

Then when the independent male bird is not paying attention, he will find an opportunity to mate with the real female bird.

According to China Science News, researchers Leif Andersson and Terry Burke sequenced the genome of male fringed sandpipers and found:

Compared with the independent type, the same chromosomal region in the satellite type and the pseudogynoid type has been transferred.

The region contains more than 100 genes, and the transformation is thought to be like a "supergene" inherited from a single gene block.

According to the "Ornithology of China", the color of the eggs of the fringed sandpiper is olive brown, yellowish brown, light green or light blue, with brown or gray spots on the cover.

In other words, the different male forms of the fringed snipe are reflected when it is still an egg.
