It was on Thursday - Karnataka High Court Questioned State Government
Will You Appoint Expert Agency To Study Habitat Of Great Indian Bustard?
The starting of year 2021 opens more possibilities / feasibility for Critically Endangered species "Great Indian Bustards - GIB. On Jan'07'2021 ,Thursday - Karnataka High Court commands State Government to submits a report by Jan'21'2021 elaborating on whether they intend to appoint a highly experienced agency like Bombay Natural History -BNHS or Wildlife Institute of India -WII to study the natural habitation of the remaining critically endangered species of "Great Indian Bustards - GIB in the state.
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.
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.
The collision of birds with power lines is one of the major causes of avian mortality. This along with electrocution results in death of millions of birds. This not only leads to significant reduction in birds’ population but also results in power disruptions.
Do you know that over 6-8 million birds worldwide meet with death due to electrocution from power transmission cables and communication towers? The one fool-proof, avian-friendly method is installing Bird flight diverter on transmission lines that can avert fatal accidents of birds and prevent damage and loss.
You may be wondering what on earth this device is and how it functions.

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.
Large birds, like flamingos, geese, swans and few endangered species, while migrating are at greatest risk. These birds can fly up to 135 kms per hour. (http://www.newworldencyclopedia.org/entry/Swan)
Due to their size and speed, these birds cannot maneuver fast. It is estimated that average 33 million birds are killed due to transmission line collision in USA alone. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4081594/
Low light conditions during dawn and dusk limit visibility of electrical transmission line conductors. Even during day time, silver colour of conductor merges with horizon, diminishing visibility.
Migrating birds usually travel in flocks. Tail end birds are most vulnerable. The ones at the front obstruct the view of birds at the tail end. Tail end birds, who usually follow birds in their front, do not get chance to change their path at last moment and collide with transmission lines. These accidents are mostly fatal as birds lose consciousness and fall to ground from a great height.
A. IndoDivert works on all type of transmission lines and towers. Its selection does not depend on capacity of transmission line.
B. Model of IndoDivert™ is selected on the basis of wind pressure/ speed in respective area, where it is proposed to be installed.
C. Clamp size varies according to conductor diameter
IndoDivert™ comes with spring loaded clamp as well as fastener type clamp. Majorly, spring loaded clamps are used for convenience and fast clamping speed.
Also, because spring loaded clamp can be mounted from a distance, as against fastener type clamp.
Our clamp design is patented.
i. We do not use metal clamps, as they increase conductive surface area of conductor and thus increase transmission loss.
ii. Mounting clamps are made using very high quality UV Stabilized, glass reinforced, weather resistant polymer, hence there are no transmission losses because of these. UV and weather resistance increase longevity.
iii. For uniform application of force by both arms of clamps, movement of clamp is controlled by polymeric gears. Non-corrosive material springs provide grip.
Installing IndoDivert™ is a very simple., though reaching installation point may be challenging.
After accessing installation point, it does not take more than 30 seconds to clamp IndoDivert™ on the conductor.
It is strongly recommended to fix IndoDivert on all conductors. When, diverter is fixed only on top (earth) conductor, it increases the risk of accident manifold. While migrating, birds fly at their best attainable altitude. Finding an obstruction, to avert accident, birds tend to dive down towards gravity, since diving down is comparatively easy (gravity helps) as compared to going up, against the gravity.
While diving downwards, birds steer themselves in between bunch of conductors which increases chances of accident multifold.
For double circuit, since phases are at same height level, we need not fix on both circuits. Fixing only on one circuit (one side) is enough.
As per guidelines laid by WII vide their letter dated 4 Feb 2019 Wildlife Institute of India has instructed to install Bird Diverters on all phases and earth/OPGW cables.
As per guidelines of Ministry of Environment, Forest and Climate Change, Government of India, vide their letter number F.No. 6-104/2019 WL dated 29.08.2019, it has been instructed that spacing between bird flight diverters should not be more than 5m to 10m. It has also been advised that Bird Flight Diverter should be visible at night.
In case of new lines, it is advisable to install diverters before electrification, post stringing.
is possible to install IndoDivert on electrified lines, as well. Here diverters are installed by specially trained technicians.
Guidelines of Wild Life Institute of India say that, for maximum visibility, Bird Flight Diverters must be installed in staggered pattern.
• For example, if there are 4 rows of conductors (1 earth + 3 phases), then first diverter is hung on the top (earth) conductor at a distance of 2.5m from tower.
• 2nd diverter is hung on top phase conductor at a distance of approx. 2.5 meters from first diverter.
• 3rd on middle phase conductor, at a distance of approx 2.5 meters from 2nd diverter.
• 4th diverter is clamped on lowest conductor at a distance of 2.5 meters from 3rd diverter.
• Further all diverters are to be placed at a gap of 5 meters from the previous one, on the respective conductor.
IndoDivert is designed to dissipate wind energy and not to allow same to pass on to conductor. It’s spinning, swaying and swing actions disperse wind pressure very efficiently and effectively.
Average weight of IndoDivert ranges from 800gms to 1200gms (depending of model of IndoDivert)
In an average span of 300 meters (between two towers), at a gap of 10 meters (between two diverters), 29 diverters need to be placed, i.e approx. 29kg weight on conductor, scattered in 300 meters. This does not affect sagging.
This weight can be very easily borne by even OPGW conductor.
Our product range includes products like scary eye, balloons etc, but performance of Bird Marker and IndoDivert Bird Flight Diverter is far better.
Eyes notice moving objects more quickly than seeing stationery objects like scary balloons etc.
IndoDivert™ has dancing dangler which besides moving, flips and rotates, thus comes in notice from a distance.
It glows during dark and its reflector reflects Sun and Moon light, which increases its visibility.
Usage of balloons etc on transmission and signal lines has minimized after experiencing results of IndoDivert- Bird Flight Diverter.
Bird Marker/ Flappers
A. Flappers are designed for low wind pressure areas and for distribution lines up to 33 Kva.
B. Size of bird marker/ flapper is small
C. Bird Marker/ flapper usually are suspended using a ring, which does not allow this to rotate and sway. This only swings
IndoDivert: Bird Flight Diverter
A. Dangler of IndoDivert, due to its swaying and rotational motion, for sure gets noticed by birds.
B. Size of IndoDivert is adequately big… to be noticed easily, but not too big so as to reduce safe distance between conductors.
C. Disk of Bird Diverter rotates/ swings and sways. Rotational movement is assisted with bearings for longevity and precision. During Swaying movement, only stainless- steel parts come in contact with each other. Moving action helps want the bird from a great distance, about presence of obstruction in their flight path.

Large birds, like flamingos, Geese, Swans and many other endangered species, while migrating, are at greatest risk of colliding with transmission lines.
Most of these accidents are fatal.
Low light conditions during dawn and dusk limit visibility of transmission lies.
Even during day time, the silver colour of conductor merges with horizon diminishing visibility.
Flying speed of these birds can reach up to 135 km/hour. Due to their size and speed, these birds cannot manoeuverfast to avoid collision.
It is estimated that on average 33 million birds are killed due to transmission line collision every year.
Migrating birds usually travel in flocks.
Tail end birds are most vulnerable.
The ones at the front obstruct the view of birds at the tail end.
Tail end birds, who usually follow birds in their front , do not get a chance to change their path at the last moment and collide with transmission lines.
These accidents are mostly fatel as birds lose consciousness and fall to the ground from a great height.
