Cape Town - Scientists have discovered there is a huge possibility that animals could be terrified of power cables due to the fact that they give off UV flashes that are unseen by the human eye.

According to the BBC an international team has identified UV (ultra violet) sensitivity in various animals according to works published in the journal Conservation Biology.

There is also a possibility that migration could be effected by the cables.

These UV flashes happen when the charges in the cables build and have to be released into the atmosphere.

Scientists form the Arctic University of Norway and University College London calculated the amount of light that is released when these charges burst.

Although we cannot see these charges the team of researchers discovered that the light held wavelengths that could be viewed by certain mammals.

According to Professor Glen Jeffery there are various species of mammals that can see some UV light.

Humans and monkeys are one of the few mammals that cannot see UV light.

The scientists began observing reindeer, what they noticed was that many reindeer avoided power lines that were running across the Arctic tundra.

Dr Nicholas Tyler, another author within the study stated that it was assumed that reindeer like many other forest animals stayed away from areas that were cleared out were pylons would soon be installed.

In the Arctic this explanation cannot be used as there are few trees, but the reindeer still stay clear of power lines.

The study suggests that various animals stay at least 5km clear of the power lines.

This study will have a global impact on the study of migration patterns of mammals.

Imagine huge flashes of light in the dark Arctic, this would most definitely deter animals from getting closer to power lines or moving between them.

The other problem is that these flashes of light are so random and unpredictable, which means that most animals cannot adapt to them.
