Bird Flight Diverters - A Solution To Avian Collision

Posted by Bird Flight Diverter on November 21st, 2020

Avian collisions came into light after decades of powerlines was developed , and hence it is not an easy task to reduce collision risk as preferences and parameters have changed from time to time. 

Avian species with high wing loading are more expected to collisions in comparison to those with lower wing loading and Avian species with short  and wide wings are the biggest sufferer in comparison to those with long and narrow wings.

Worldwide researchers suggested the following measures which can help in reducing  Avian Collisions:-

Existing Power Lines

New Power Lines

Monitoring Collision Causes

Spatial analysis -Behavior, Species , habitat

Avian risk assessment

Field assessment to identify species, abundance, and high avian flying areas.

Line Markers -Flappers/Bird Diverters

Avian risk assessment to evaluate collision

Developing Surrounding lands

Line Placement in Migrating Areas

Removing the shield wire (wherever possible)

Line orientation- biological and environmental factors

Changing Wires Configuration

Line configuration

Rerouting Lines 

Line Markers to increase visibility - Flappers/Bird Diverter

Undergrounding Overhead Line Wherever Possible 

Mostly all studies have well-elaborated an outstanding reduction in a collision and an immaculate increase in avian behaviour by avoiding powerlines at marked lines (with avian balls, flight diverter) in comparison of unmarked lines, but these results may vary many factors such as location, avian species and kind of marking devices. Other observation also proves that avians reacted towards a marked line quite early rather than the unmarked one.

Observing the flying behaviour of avian species near powerlines can be very effective in identifying & reducing the potential risk for collisions.

  • Flocking

  • Flying patterns of migrating and non-migrating birds.

  • Nest building, and Feeding flights to and fro.

Basically, there are two types of migrating avians:- 

  1. Long Distance

  2. Daily Players 

Overall all a big drastic change has been observed in  avian behavior at marked and unmarked lines. Their reaction varies with kind of lines.

Avian mortality with powerlines can be reduced by below-mentioned scenarios:-

  • Line Marking (Spirals, Bird Diverter)

  • Managing Surrounding Land

  • Removing The Shield Wire

  • Changing The Diameter Or Configuration Of Wires,

  • Rerouting or Undergrounding Existing lines wherever Possible.

Commonly there are 5 types of line marking devices:-

  • Marker Balls

  • PVC spirals

  • Flappers

  • Bird Flight Diverters

  • Illuminating Led Diverters

MODIFYING EXISTING LINES

  • Line Marking

  • Managing Surrounding Land

  • Removing The Shield Wire

  • Changing The Diameter Or Configuration Of Wires

Rerouting or Undergrounding Existing lines wherever Possible. Commonly there are 5 types of line marking devices :-

  • Marker Balls

  • PVC spirals

  • Flappers

  • Bird Flight Diverters

  • Illuminating Led Diverters 

All the above mentioned devices are highly sophisticated and well upgraded with times. The outcome of these devices may vary depending upon several sensitive conditions such as, weather, location , Species , availability of devices between the two towers etc. But yes we also can't deny that out of all these marking devices bird diverts proved to be one of the best solutions worldwide.

Different companies have different suggestions for their product spacing, but the standard spacing recommended around the globe:- Bird Flight Diverter to be installed at an interval of 5m to 30m i.e. 16ft to 98ft is mostly followed.

Researchers states that Implementing the above Guidelines will play a major role in  reducing avian collision.
