-----The Challenge
Our Skies Are Shared. Our Infrastructure Creates an Invisible Threat.
Across India's expanding energy network, over 90,000 circuit kilometres of high-voltage transmission lines intersect with critical wildlife habitats, migratory corridors, and protected areas. Power lines, earth wires, and stay wires are effectively invisible to birds — especially in fog, low light, and at flight speeds above 40 km/h. The consequences extend beyond wildlife. Bird strikes on conductors trigger flashovers, line faults, and unplanned outages — creating measurable grid reliability risks and costly emergency repair mobilisations for transmission operators. The critically endangered Great Indian Bustard — fewer than 150 individuals remaining — faces power line collision as a primary extinction threat. The Supreme Court of India has directed mandatory Bird Flight Diverter installation across GIB habitat corridors as a priority conservation measure. This is simultaneously a conservation emergency, an infrastructure reliability challenge, and an ESG compliance imperative — requiring an engineered solution, not a compromise.
Why Birds Cannot See Power Lines
Large birds with high wing loading have limited maneuverability
Heavy-bodied birds with high wing loading struggle to change direction quickly, making them more vulnerable to power line collisions
Low Visibility Hazards
Power lines, earth wires, and opgw wires are thin, high-contrast against sky only under ideal conditions — and effectively invisible to birds at high speed, in fog, or at dawn and dusk.
Infrastructure Risk
Bird-strike-induced conductor flashovers create real grid reliability and revenue risks for transmission utilities — beyond the conservation consequences of every avian collision.
Habitat Intersection
India's expanding energy and communication networks increasingly cross vital migratory routes, Ramsar wetlands, Protected Area boundaries, and Important Bird Areas (IBAs).
--Our Solution
A Suite of Engineered Bird Flight Diverters
Three purpose-designed devices — each optimised for a specific risk profile, visibility requirement, and deployment environment. All CEA-compliant. All utility-approved. All backed by a 5-year warranty and 15-year design life.
Non Led Bird Flight Diverter
Power Line Non Led Bird Flight Diverter
The non-LED bird diverter provides cost-effective collision prevention for standard transmission line applications. Constructed from UV-stabilized polymers, these bird flight diverters attach directly to overhead conductors and create high-contrast visual markers visible during daylight operations. This configuration suits general transmission corridors where diurnal avian activity represents the primary collision risk. The rotating swivel design rotates in wind conditions, enhancing dynamic visibility while maintaining structural integrity under mechanical stress. Material composition includes UV-resistant polymers tested to withstand continuous solar exposure, temperature cycling between -40°C and +80°C, and wind speeds exceeding 150 km/h. Installation requires no special tools and integrates with energized line maintenance protocols.
Power Line Led Marker
LED Bird Diverter
LED bird flight diverters incorporate solar-powered LED technology for enhanced visibility during dawn, dusk, and nocturnal periods. Each unit contains photovoltaic cells that charge internal battery systems, activating LED arrays during low-light conditions. This technology addresses collision risks in high-sensitivity corridors including migratory pathways, wetland crossings, and areas with documented nocturnal avian activity. The flashing LED pattern increases detection range compared to passive markers, particularly for species with reduced low-light visual acuity. Battery systems provide minimum five-year operational life with zero maintenance requirements. LED modules withstand voltage-induced electromagnetic interference and operate reliably across transmission voltages from 132kV to 400kV.
Conservation Emergency · Great Indian Bustard
India's Rarest Bird Is Running Out of Safe Sky.
Fewer than 150 Great Indian Bustards survive in the wild. The Supreme Court of India has mandated Bird Flight Diverters on all power lines passing through GIB habitat — GIBs cannot detect thin conductors until impact is unavoidable — their eyes face sideways, and at 15 kg they cannot dodge at the last moment. The Wildlife Institute of India estimates ~18 GIBs are killed by power lines every year, making collisions the single largest cause of extinction
SUPREME COURT OF INDIA — RANJITSINH & ORS VS. UNION OF INDIA, 2021 · MANDATORY BIRD FLIGHT DIVERTER ORDER
"There are some things that no amount of money can ever bring back once they are gone. The priority should be to save the near-extinct birds — irrespective of cost".
The Supreme Court directed mandatory Bird Flight Diverter installation on all overhead lines in GIB corridors that cannot be undergrounded — making BFDs a nationally court-mandated conservation measure. Prakritis Technologies diverters are actively deployed across Rajasthan and Gujarat GIB zones and hold formal approvals from GETCO and RVPN, the two state utilities responsible for transmission infrastructure in India's primary GIB habitats. Our LED model provides active blinking illumination at dawn and dusk — the exact periods of peak GIB flight activity and highest collision risk.
New India powerline ruling is lifeline for Critically Endangered bustard
The Great Indian Bustard is on the brink of extinction. Collision with powerlines is the biggest threat – but hope is at hand. This year, the Indian Supreme Court ruled that all powerlines should be taken underground at its breeding stronghold – a lifeline for this and many other bird species.
Climate litigation has entered the room. But could great Indian bustards be inched out?
A recent Supreme Court order stated individuals had the right to be free against the adverse effects of climate change, which legal experts say could open the door to more climate litigation in India
With less than 150 Great Indian Bustards remaining in the wild, what’s driving their extinction?
The Centre has told the SC that it is not possible to comply with the court's order to put power lines underground, even as they crisscross the Godavans' habitat. What exactly is the nature of the threat, and what has the Centre argued?
Bird Diverter in Transmission Line
"The Significance of Bird Flight Diverter"
A power line marker, also known as a bird flight diverter, is a device or system designed to visually deter birds from flying into obstacles such as power lines, wind turbines, transmission towers, etc. Bird flight diverters aim to reduce bird collisions, protecting both birds and infrastructure. These devices typically use visual cues to alert birds to the presence of obstacles, helping them change flight paths.

Common Questions
Frequently Asked by Engineers and Procurement Teams
Technical questions from transmission engineers, EPC contractors, and procurement heads — answered with the precision they require. Ask Our Technical Team
What is a bird flight diverter and how does it prevent avian collisions?
A bird flight diverter is a device installed on overhead conductors and earth wires that increases their visual detectability to birds in flight. Birds approach power lines at speeds where reaction time is insufficient to avoid invisible conductors. Diverters provide visual contrast through retroreflection, photoluminescent glow, dynamic rotational motion, and — in LED models — active blinking illumination. This gives birds sufficient detection distance to alter their flight path safely.
How Do Bird Flight Diverters Work?
Bird flight diverters work by making structures more noticeable to birds. They often use bright colors, reflective materials, or movement to catch a bird's attention. When birds see these diverters, they can alter their flight path to avoid collisions.
Where Are Bird Flight Diverters Used?
Bird flight diverters are commonly used on:
Power Lines: To prevent birds from colliding with electrical transmission and distribution lines.
Wind Turbines: To make the blades more visible and reduce bird strikes.
Communication Towers: To enhance visibility and protect birds flying near these structures
How Are Bird Flight Diverters Installed?
Bird flight diverters are typically installed by trained technicians. The installation process varies depending on the type of diverter and the structure it is being attached to. Safety is a priority during installation to protect both the workers and the birds
What type tests have been conducted on the products?
Products undergo: Mechanical Strength (clamp slip ±25kg, pull +100kg), Vibration, Temperature Cycle (-20°C to +100°C), Heating Cycle, Radio Interference Voltage / Visual Corona, Corrosion Resistance, Accelerated Ageing, and Visual Examination tests. Full type test reports are available to procurement authorities on request.
When should I specify LED versus Non-LED diverters?
LED models (PLM/LD-V1) are recommended for high-risk zones requiring 24-hour active protection — near major migratory routes, GIB habitat corridors, airports, and areas with significant nocturnal flight activity. Non-LED models (PLM/NLD-V1) provide effective daytime and transitional-light protection through retroreflection and photoluminescence, and are optimal for standard network deployment where active illumination is not mandated. A risk-zoned approach — LED at hotspots, Non-LED on standard spans — is common best practice.
What is the price of bird flight diverters in India?
Bird flight diverter prices in India vary based on type (LED or Non-LED), quantity, and project specifications. Prakritis Technologies supplies CEA-compliant diverters for bulk transmission projects. Contact us via birddiverter.com for a project-specific quotation.
Which birds are most at risk from power line collisions in India?
The Great Indian Bustard (GIB) is most critically at risk — fewer than 150 survive in the wild and power line collisions are the leading extinction threat. Other vulnerable species include Sarus Cranes, Lesser Floricans, flamingos, and large migratory raptors using India's transmission corridors.
