Dave,
There are more problems than usual here for birds. The whole area is a bird sanctuary. It is all marshes and saltings. Therefore there is a much larger population of bigger birds. It is very windy at times, when a bird is flying with the wind it comes upon the wires 2 or 3 times faster than normal, it does not have time to react.
Larry,
No way would the government spend money on helping anybody or any creature, thats not their job. The power company does this not because it likes birds in any way, only to reduce the cost of repairing the wires which get broken when a large bird hits them.
Interesting. I would not have guessed that birds would have problems with the wires. In the States there are large orange spheres attached to power lines that are located near airports or in other places that airplanes are known to frequent.
