WMSv2 — Best Bird Flight Diverter for Critical Transmission Corridors

The IndoDivert WMSv2 is Indolite's advanced-generation dynamic bird flight diverter engineered for the highest-priority bird protection zones in India. As a premium No-LED bird diverter, the WMSv2 features a dual-bearing rotation mechanism and next-generation phosphorescent glow-in-dark coating — delivering superior performance in critical ecosystems where standard single-bearing models may not suffice.

The WMSv2 is widely recognised as the best bird flight diverter in the non-LED category for Important Bird Areas (IBAs), Wildlife Sanctuaries, and critical bird flight diverter in transmission line corridors where the Great Indian Bustard (GIB), flamingos, cranes, and migratory waterfowl are present.

🏆 Best Non-LED Bird Diverter for IBAs: WMSv2 dual-bearing activates at wind speeds as low as 2–3 km/h vs 8–10 km/h for single-bearing models. In sheltered forest crossings and valley corridors with low wind, the WMSv2 continues spinning and alerting birds while other models sit stationary.

How WMSv2 Works — Dynamic Bird Diverter Mechanism

The WMSv2 illustrates advanced how bird diverter works engineering through a multi-layer protection system:

• ⚙️
  Dual-Bearing Ultra-Low Wind RotationActivates at 2-3 km/h wind — creates continuous spinning motion visible to birds 250m+ away. Essential for low-wind forest crossings where single-bearing BFDs fail to rotate.
• 🌑
  Enhanced Glow-in-Dark Formula (Extended Emission)Next-gen phosphorescent coating: longer charge retention + brighter night emission vs WMSv1. Provides extended passive marking for dawn/dusk active species.
• 🔴
  High-Visibility Red RetroreflectorReflects ambient light from all directions — supplementary passive night visibility even in calm conditions.
• 🛡️
  Wildlife Protection Device — Forest Dept AcceptedAccepted as a certified wildlife protection device by Forest Departments, State Wildlife Boards, and MOEF&CC for all line clearance applications.

FAQ — WMSv2 Advanced Bird Flight Diverter

Is WMSv2 the best bird flight diverter for IBAs in India? ▾

Yes. WMSv2 is widely considered the best bird flight diverter in the non-LED category for Important Bird Areas (IBAs) across India. Its dual-bearing low-wind activation and enhanced glow-in-dark formula deliver maximum protection — and it is accepted by Forest Departments and Wildlife Boards as a compliant wildlife protection device.

How does WMSv2 work as a bird deterrent on transmission lines? ▾

WMSv2 works as a bird deterrant by spinning on the overhead conductor at very low wind speeds (2-3 km/h) — creating a visible motion alert that birds detect from 250m+ and naturally avoid. At night, enhanced glow-in-dark coating passively marks the power line. This is how bird diverter works in the advanced dynamic non-LED category.

What is the difference between WMSv1 and WMSv2 bird diverters? ▾

Both are no-LED bird diverters. WMSv1 uses single-bearing rotation (activates 8-10 km/h wind) — best for standard projects. WMSv2 uses dual-bearing rotation (activates 2-3 km/h wind) + enhanced glow-in-dark formula — best for critical IBAs, wildlife sanctuaries and sheltered forest crossings.

Is WMSv2 approved as a wildlife protection device? ▾

Yes. The WMSv2 is accepted as a wildlife protection device by MOEF&CC, State Wildlife Boards, and Forest Departments across India. It meets all requirements for Forest Clearance on transmission line projects through protected areas and eco-sensitive zones.

Powerline Collisions & Bird Flight Diverters

Powerlines always pose a great threat to avian species worldwide. The ratio of avian mortality increases due to collision with powerlines, whether its electricity transmission tower or distribution networks.

The thrust of being more & more modernized, where electricity plays an important role, unfortunately, the major part of the world is found to be surrounded by threatening powerlines.

The Powerline network acts as a very dangerous barricade, as they lead to an effective hindrance between feeding and resting paths of avian species. The most common sufferer in the said cause are species with a huge body and low frontal vision. Weather conditions over the years also play a major role in increasing the risk of collision and led to increased mortality.

Collision is always considered as an effective cause of death different from electrocution. Avian species and agile birds which normally migrate during the night at an average height of 20-50 meters, flying in groups are found to be less affected in comparison to others. The probability of evaluation and mitigation of power transmission networks considered to be the most affecting features of avian mortality.

Others Factors affecting Avian species populations

• Habitation

• Destruction Of Breeding Colonies

• Illegal Hunting

• Collisions With Electric Power Lines.

Around the globe researchers well elaborated the said problems in multiple ways and also suggested the most suited line marking devices to reduce mortality due to collision with powerlines. Where Bird Diverter is the most common name always. Installing these bird diverters can be considered as the most effective as well as an economical solution when it comes to collision with powerlines.

Researchers also suggested that the below-mentioned scenarios for best possible results:-

• Space between two Bird Diverters, fixed on power transmission lines near forests, water bodies, creeks, landfills, forest lands or areas which fall directly in flight path of avians should not be more than 5 meters.

• Space between two Bird Diverters, fixed on power transmission lines , beyond 2 kms of forests, water bodies, creeks, landfills, forest lands or areas which fall directly in-flight path of avians, gap may go up to maximum 10 meters.

Performance of these diverters can be classified on the basis of their durability, stability as well as compatibility with the zone they have been used for. The  main idea of getting these simple devices installed on power transmission lines is to make them easily visible to avian species during their flight while migrating from one place to another, so that they are well aware of the obstacles in advance.
