Why do animals avoid getting close to high voltage poles?

Many people wonder why animals tend to avoid grazing near high voltage poles or cables.

Scientists from universities in England and Norway believe they have explained this mystery after discovering that ultraviolet (UV) light from high-voltage grids cannot be received. know by human eyes, but can be seen by birds and some mammals. According to a recent study, about 35 species of animals including dogs and cats can see the light that humans cannot see.

This may be the reason some animals do not avoid grazing near high voltage poles or cables. Scientists believe that reindeer sees UV light in the Arctic and this ability even helps them detect polar bears.

The conclusion comes after a team of scientists from the Royal College of London, the Moorfields (UK) ophthalmic hospital, the Arctic University and the University of Oslo (Norway) conducted a study on whether high poles Does that affect negatively on the population of reindeer species?

The wild reindeer species in Norway can sometimes be divided into small herds because they cannot move freely due to the high voltage grid. This led to the formation of 23 different reindeer herds in southern Norway.

Professor Glen Jeffery of the Royal College of London, said: 'New information about the animal's visual acuity and the characteristic of the high-voltage grid, provides clear evidence that animals avoid high power grids. That's because they have the ability to detect UV light emitted from the grid , making them afraid. '

By choosing to avoid the high voltage grid, animals like reindeer face intermittent migration and lose grassy areas. This may affect the movement speed and genetic diversity of the species.
