In the early morning of February 7, surveillance cameras captured a shocking scene in a certain area of the Mexican state of Chihuahua.
On the originally calm residential streets,
Suddenly, a large black shadow fell from the sky.
The black shadow fell rapidly downwards, hitting the ground at the same time, and scattered into hundreds of dense black dots.
It turned out that these were hundreds of blackbirds.
Most of the birds flapped their wings again and flew away, leaving large areas of bird carcasses on the ground.
When local residents got up, they saw dozens of blackbird carcasses on the ground and rushed to report to the police.
Police arrived at the scene at around 8:30 a.m., followed by veterinarians who were also present to investigate.
The birds were identified as yellow-headed blackbirds and had recently flown south from Canada to Mexico for the winter.
The preliminary judgment of the on-site personnel is that the local use of wood-burning heating equipment and agrochemicals causes air pollution.
The birds may have caused accidents because they inhaled toxic fumes, or because too many birds were gathering on the wires at the same time.
Of course, these are only speculations for now.
Some netizens speculated that it may be that the leading bird has an abnormality, and the follower has been deviated.
After the birds in front hit the ground and died, most of the birds flew away again.
Richard Broughton, an ecologist at the Uk's Centre for Ecology and Hydrology, agrees with this speculation.
The expert said that although the video footage did not capture the raptor,
But he was 99 percent convinced that the "mass death of the yellow-headed black oriole" was caused by predatory birds.
"It should be caused by birds of prey such as eagles and peregrine falcons chasing flocks of birds in the sky."
In the crowded flock of birds, the birds simply follow the birds in front of them.
When attacked by birds of prey, flocks of birds are too close to the ground and buildings to have enough flight space to make sharp turns.
As a result, a large "black shadow" hit the ground, and a rear-end accident occurred, resulting in inevitable deaths and injuries.
In addition, a "bird rain" also fell in a coastal village in Wales last week, with as many as 200 starlings dying mysteriously.
At around 8 p.m. on February 10, driver Michaela Pritchard drove through the scene.
She found a large number of bird corpses scattered on the road and grass, and she was startled and rushed to report to the police.
Claire Eaton, a local resident, said she had seen a bolt of lightning in the sky.
"It's horrible, the road is full of bird corpses, like the plot of a horror movie."
Afterwards, she brought back a starling that had survived the fright, intending to take care of it for a few days before releasing it.
Another witness, resident Ian Mccaffrey, revealed:
"I heard a loud noise when I got off work, and then a bunch of birds fell from the sky like raindrops on the roof of a car."
Dominic Couzens, a 59-year-old bird expert, was interviewed:
"These birds may have been frightened by something, maybe it was a loud noise.
An unexpected thing that makes them frightened and disoriented, and then crash into a foreign object..."
The exact cause of the incident is still inconclusive,
But the picture of the collective death of these birds does look quite terrifying.
Some foreign netizens exclaimed: "This is simply the end of the world!" ”
