Authorities in Cuauhtemoc have begun investigating the causes of the deaths of hundreds of birds. An animal husbandry vet who was in the area was called to assist with the investigations. Although there is no definitive answer yet, the specialist works with two hypotheses. The first is that the birds may have inhaled toxic smoke from a nearby building. It also deals with the possibility of birds being subjected to electric shocks by high voltage cables.
In an interview with the British newspaper “The Guardian”, ecologist Richard Broughton cited a third theory. According to the expert, “It seems that a predator, such as a hawk, pursued the herd, as it does with starlings, and fell when the herd was forced down.” “You can see that they are acting like a wave at first, as if they were being pushed from above,” he added.
As Alexander Less, a professor at Manchester Metropolitan University, told the Guardian, he agreed with the ecologist’s theory. For him, the flock flew in a group to avoid predatory birds and ended up falling to the ground. Despite the hypotheses surrounding the case, there is no definitive answer yet. Specialists are waiting for the autopsy report to come to a concrete conclusion about what happened.
