These impressive images show dozens of birds dropping dead in Mexico (video)

In impressive footage from a surveillance camera, dozens of birds can be seen dropping dead on a street in Chihuahua, Mexico. According to a local veterinarian, the birds might have died following inhaling toxic fumes from a nearby heater or due to overloaded electrical cables.

However, the authorities have not officially pronounced on the causes of the death of all these birds. These would be yellow-headed blackbirds that migrate from northern Canada to Mexico for the winter.
