Reducing Avians Collision With Bird Diverters

Very often in the past, we all must have driven great memories of multiple places. If you remember those colour full balls/spheres hanging vertically from power transmission lines, you might have wondered about what purpose they serve…This curiosity disappears as soon as we are more busy with joy & laughter. Some point of time we also think that these are the leftovers of decorations which someone forgets to take down. The reality is that they are known as bird diverters basically used to divert birds and save aviation transport.

These Bird flight diverters are very common, whenever topics like Power Transmission lines/ Power generations/ power distribution and HVL comes in the discussion. These Bird diverters are also addressed as powerline markers. Few international federations also mention them as visibility markers, as these diverters guide avian species to identify power lines related obstacles much prior while migration from one place to another.

Around the globe top, most researchers suggested and recommended the best available Bird diverters as mentioned below:-

• Bird Flight Diverter
• Aviation balls
• Flappers
• Strippers
• Dynamic Bird Flight Diverter
• Led Bird Flight Diverter

Yet it’s very difficult to comment on the efficiency of these diverters as it depends on many features like kind of species, location, weather condition, level of flight frequency etc.

Many expert studies also elaborate and well-proven that the presence of bird flight diverters is associated in decreasing avian collision with power transmission lines and accordingly reduces mortality.

During multiple research and observations it has been found that after the installation of bird flight diverters, there is a tremendous change in the flying habits of avian species. They have reacted further away from marked lines in comparison to non-marked ones. Such a phenomenal reaction of avian species at greater distance results in reducing the number of avians victims with power transmission lines. These observations show the positive effects of reducing the number of avian collisions with power transmission lines. The reduction rate in avian collision with power lines after installing Bird diverter is recorded up to 93%. Avian collisions with power transmission lines is a very sensitive issue and need to be rectified by taking proposed precautions to reduce the ratio of mortality.
