Supreme Court steps in to protect Great Indian Bustard

 


By- Krishnadas Rajagopal 



The Supreme Court on Monday swooped-in to intervene on behalf of the critically endangered Great Indian Bustards over the birds falling dead after colliding with power lines running through their dwindling natural habitats in Gujarat and Rajasthan.

A Bench led by Chief Justice of India Sharad A. Bobde will examine on a priority basis whether overhead power cables can be replaced with underground ones to save one of the heaviest flying birds on the planet.

Attorney General K.K. Venugopal, appearing for the Power Ministry, however submitted that only low voltage lines can go underground but not the high voltage ones.

The court found further that an alternative mechanism — to install flight bird divertors — to guide the birds away from the power lines would be expensive. In fact, the court discovered that the divertors, with their recurring costs, would end costing more than installing and maintaining underground lines.

But the court suggested treading the middle path.

Bird Flight Diverters A Miracle For Avian Species

Multiple Exploration around the globe well elaborates avian mortalities caused by human-made infrastructures, in the race to provide better and upgraded amenities. These facilities are further divided into three different segments which are increasing day by day:-


  • Transmission Lines

  • Communication Tower

  • Wind Turbines


Acquiring the actual probability of avian population mortality is not an easy task with a frequent increase in the above-mentioned facilities. The level of threats to avians species from the said facilities continues to increase.


Transmission Lines always act as one of the biggest trouble/factors for avian species collisions as compared to other facilities. Powerlines have phase-to-phase and phase-to-ground wire clearances, which leads to avian landing / resting on the Powerline towers and further leads to increased risk of completing the circuit often resulting in electrocution and power failure.


Transmission lines where overhead ground wires are mostly smaller in comparison of the phase conductors are more expected to create bird collisions. Eliminating fixed wires and protecting energized conductors with surge arresters should be taken into consideration wherever possible. The discussed factors are pretty much expensive and even not feasible at all locations. Hence industry leaders came up with an alternative economical solution to reduce avian collisions at powerlines by introducing wire marking devices such as:-






  • Aerial Marker Spheres

  • Spiral Vibration Dampers

  • Conductor Cover-Up

  • Swinging Plates

  • Bird-Flight Diverters

  • Flappers.


Few marking devices that physically enlarge the wire work as a wind sensitive device, inspiring snow during winters automatically increases the risk of wire and power break down due to line tension and stress loads. These devices may also cause physical damage to the conductors.

The output of Bird Diverters was always found up to the mark when it comes to either avian collision or population factors. Different Bird diverters have different specifications and probabilities and hence they cannot be compared among themselves. The efficacy of a few bird diverters that are specifically targeting particular species can hardly be questioned. Bird Diverters execution is well explained if these diverters are easily noticeable and act as a predator to endangered and vulnerable species.


Researchers further state that wherever Bird diverters are installed there should be a min spacing of 5 meters or 16ft between each of them because the probability of collision automatically decreases when the space between bird flight diverters is less.


The brief of worldwide studies well elaborates that Bird Flight Diverters are the most potential rescuer in saving avian species.

Bird Diverters Installation Is A Must On Power Lines- As Per NGT

The myth about the Great Indian Bustard (GIB), Powerlines and Bird Diverters is always a very sensitive point of discussion from decades. Multiple seminars, meetings and conferences were held around the globe from time to time by different wild life-saving associations, federations and other prominent governing bodies. Recently it was on 04-04-2019 ref "Original Application No. 385/2019" when Hon'ble National Green Tribunal -NGT has directed The Ministry of Environment, Forest and Climate Change - MoEF&CC to furnish a accurate report on the deaths of Great Indian Bustard within 2 months. The said report (FACTUAL REPORT ON THE GREAT INDIAN BUSTARD RECOVERY PROGRAM) was finally submitted to The Registrar of  Hon'ble National Green Tribunal -NGT  on 11-07-2019 by Deputy Inspector General MoEF&CC. After going through the facts and figures as elaborated in the above mentioned  factual report, The National Green Tribunal -NGT found that steps taken are not adequate and there continues to be high mortality of the birds.


Hence later this year on 23-12-2020{(Original Application No. 385/2019) -(IA No. 333/2020)}  The National Green Tribunal - NGT passed an order during which it has been directed that the installation of “bird diverters” on power transmission lines should be done on priority basis in order to protect the critically endangered Great Indian Bustard (GIB).

 

The Crucial Points of The National Green Tribunal -NGT Order (mitigation measures for

protection of Great Indian Bustard (GIB) are:-

 

  • Bird Diverters Installation on power transmission lines is Mandatory.


  • Under-grounding of transmission lines needs to be insured for all new projects by making it mandatory under the Water/Air Acts by the concerned State PCBs which may be overseen by the CPCB and the MoEF&CC.”

  • Route planning

  • Vane tips of the wind turbine shall be painted with orange colour to avoid bird hits

 

 

The National Green Tribunal -NGT has strictly directed the MoEF&CC/CPCB/State PCBs to take further action as per the plan suggested by the six-member committee appointed by the Tribunal itself.


In the final verdict, The Court inclined the matter by directing that all mandatory steps be taken for preserving critically endangered Great Indian Bustard (GIB) by installing bird diverters on all existing power transmission lines as suggested by the six-member Committee of the MoEF&CC. It has further directed that  Monitoring of compliance be done, preferably by the Wildlife Institute of India at least twice a year.


The Court has considered the report submitted by the Committee and directed it to finalize the proposed action plan within two months.

There has been a drastic  decline by 75% in the population of the Great Indian Bustard (GIB) since the last 3 decades. The main reason for these declines is lethal accidents /collisions with power transmission lines.

Why Do You Need a Bird Flight Diverter?

A Bird Flight Diverter (BFD) is a device installed on overhead power line conductors to enhance their visibility to birds in flight — preventing fatal bird-wire collisions and protecting both wildlife and power infrastructure. India's Central Electricity Authority (CEA) and Hon'ble Supreme Court of India has made Bird Diverter installation mandatory on all transmission lines near Great Indian Bustard habitation, and eco-sensitive zones. Indolite BFDs are the only ones in India, approved by CEA, for installation in these areas.

Dynamic Bird Flight Diverters
Wind-activated rotating models — Significantly Enhance power line visibility

Dynamic Bird Flight Diverters are wind-activated rotating devices that swing, sway and rotate on the power line conductor, creating continuous motion-based visual alerts. The 3D motion makes them significantly more Prominent and Visible as compared to static markers — alerting birds like eagles, vultures, cranes and the critically endangered Great Indian Bustard about presence of obstruction in their flight path. CEA specifically recommends dynamic BFDs for eco-sensitive zones and Important Bird Areas (IBAs).

IndoDivert Bird Flight Diverter clamps are custom engineered for respective conductors. This ensures a robust, non slip grip without pinching the conductor and eliminates the need for rubber linings to compensate for size mismatch.

In contrast, universal adjustable clamps inherently provide lower grip strength. Because of this lighter grip, to avoid slippage and falling, manufacturers are forced to reduce the warning disk size, which directly compromises visibility and long distance detection.

IndoDivert's warning disk is the largest and strongest in the segment. While others typically offer a 3–4 mm thick disk, Indolite uses a 20 mm thick collar reinforced disk, engineered to withstand high wind pressures, gusts, and repeated wind lash impacts without deformation.

The warning disk is the core functional element of any bird diverter — it is the component that alerts birds to an obstruction in their flight path. Any reduction in disk size or structural strength reduces the diverter's effectiveness.

  • 🌀
    Wind-Activated RotationSpins automatically with wind — no power, no battery needed. Motion creates the most effective visual alert for birds.
    At high RPM, warning disk of BFD can become invisible (like blades of fan become invisible at high speed). IndoDivert's modulated rotation mechanism governs RPM, thus ensures visibility.

Static (Non-Dynamic) Bird Flight Diverters
Fixed passive markers — No moving parts · Lowest maintenance · CEA Approved

Static Bird Flight Diverters (BFDs) are stationary overhead power line markers designed with no moving parts. Their primary function is to increase the apparent size of conductors, making overhead power lines more visible to birds and reducing the risk of collisions. With zero maintenance requirements, static bird diverters are among the most cost‑effective solutions for avian protection. However, compared to dynamic bird flight diverters, they may attract less attention from birds due to the absence of movement or light‑based features.

Frequently Asked Questions — Bird Flight Diverters

What is the difference between LED and Non-LED Bird Flight Diverters? ▾
Non-LED (WMSv1, WMSv2) use glow-in-dark phosphorescent material — they charge in sunlight and glow passively at night. Zero power needed. LED models (NFv2, NFv3) have solar-powered LEDs (6 visible per face) that actively illuminate at night, providing far greater visibility (300–400m+) for birds. LED models are recommended for the highest-risk corridors — GIB habitats, flamingo flyways, and crane migration routes.
What is the difference between WMSv1 and WMSv2 bird diverters? ▾
WMSv1 is the standard entry-level dynamic bird diverter with a single-bearing rotation system — ideal for areas with regular wind. WMSv2 features an upgraded mechanism equipped with RPM governor, enhanced glow-in-dark material with longer emission duration, and is specified for high-priority bird corridors and Important Bird Areas (IBAs) where maximum protection is required.
What is the difference between NFv2 and NFv3 LED bird diverters? ▾
NFv2 is Indolite's standard LED dynamic bird diverter with 6 LEDs per face and solar charging — providing 300m+ night visibility. NFv3 is the latest generation with an upgraded high-efficiency solar panel, brighter LED array (400m+ visibility), and improved all-weather bearing system. NFv3 is recommended for the most critical corridors including Great Indian Bustard (GIB) habitats as per MOEF&CC guidelines.
What is a Helical/Spiral Bird Flight Diverter and why is it widely used? ▾
A Helical Bird Diverter (also called Spiral Bird Diverter) is a coil-shaped marker that wraps 360° around the overhead conductor — apparently magnifying size of conductor making it visible to approaching birds. Indolite's IndoDivert Spiral is made from UV-stabilised yellow polymer, clips on conductor/OPGW, requires zero maintenance. Since it is static, its use as a power line marker is discouraged, as it is considerably less effective than dynamic bird diverters.
Which bird diverter model should I choose for my project? ▾
Dynamic Bird Flight Diverters are strongly recommended over Helical diverters. Choose based on your line location:
• WMSv1 — Standard bird habitat zones, 33kV–110kV lines
• WMSv2 — High-priority IBAs, critical wildlife corridors
• NFv2 — Lines near GIB habitats, flamingo/crane flyways
• NFv3 — Most critical night-flyway corridors, MOEF&CC mandated zones
• Spiral/Helical — In low flying zones, generally like a line marker
• Static - Clip On Type — In areas designated as low-flying zones.
