Flock of birds drop dead in northern Mexico (video-photos)

An explanation could be windshear, a strong vertical downward wind that has caused even airplanes to crash

Sectional Police of Alvaro Obregon reported that close to a hundred yellow-headed blackbirds that migrate from Northern Canada to Mexico for the winter dropped down to their death.

A local veterinarian reported to the police that the birds could have died after inhaling toxic fumes from a heater nearby or because of an overcharge from electricity cables.

Another explanation could be windshear, a strong vertical downward wind that has caused even airplanes to crash.

Nevertheless the authorities still don’t know what caused the deaths.
