As human population expand, our greed too. Growth in electricity network, causing substantially damage to bird’s population, like mostly collision with electricity line. as per my knowledge, there are two ways to prevent death from electricity, like if it is high or medium power voltage lines, then we made underground line, and if it is low voltage line then we do insulation of line, but it is much expensive and laborious. So, is there any other methods or interdisciplinary approach to avoid death of birds?
Mostly medium to large size birds face obstacle during flight like Crane sp, Bustard, peafowl, Flamingo etc
The question should be clarified.
1. How many birds do get killed.
2. What causes death? Electricity och collision?
3. Birds fly on different heights over ground/canopy. How will that affect the number killed.
Birds do not fly randomly, at least not migrating birds. Thus, placement of power lines in the landscape is important.
Power lines will affect vegetation and will change animal behaviour.
That is the catch. When installed, the lines have changed the habitat, rendering the pre-study outdated. One might consider developing an interdisciplinary model taking this into account.
Jonas R. Persson , i am very grateful, for your reply. well, i do not have yet exact number that how much birds die annually due to electricity lines, but i often see them hanging over lines or on the ground, also often come into news (when number is high or species is important for conservation), but i was curious to know more about it, and i am 100% agree with you, that there is need for interdisciplinary approach, due to installation of power line without assessment, it impact on birds, thus vegetation, may entire landscape could be change.

, this is really new for me that, like if they are constructing dam or infrastructure in protected area, study is quite obvious but before installing power line, they try to asses impact on nature, it is not widely famous, may be not in developing country.thank you
Hi.
In the Canary Islands there are several studies about the impact of electric power lines on birds. After the first results some measures to avoid this problem were adopted, mostly in two islands (Fuerteventura and Lanzarote), and there are positive results (at least in some areas), as the mortality rate by this cause has clearly diminished.
