I got interested to study a bit more about the idea that birds’ magnetic compass orientation would get disrupted by electromagnetic noise. There has been a debate on does electric and magnetic fields affect biological processes and human health and when the article was written, in 2014 there hadn’t been any scientifically proven effects.
Svenja Engels, Nils-Lasse Schneider, Nele Lefeldt, Christine Maira Hein, Manuela Zapka, Andreas Michalik, Dana Elbers, Achim Kittel, P. J. Hore & Henrik Mouritsen performed controlled experiments in the University of Oldenburg and found out that European robins lose their ability to use the Earths’ magnetic field when exposed to low-level AM electromagnetic noise between around 20 kHz and 20 MHz, the kind of noise routinely generated by consumer electrical and electronic equipment. The birds gained the ability back to orient to the Earths’ magnetic field when they were shielded from electromagnetic noise in the frequency range from 2kHz to 5 MHz or tested in a rural setting.
I found a European Commissions’ Guidance for Energy Transmission Infrastructure from 2018. This is only a guidance in a sense that I am not sure if these are actually taken into account when making decisions about energy infrastructure. What I found interesting in this guidance is that they address that biodiversity is an important element and nature provides important socio-economic benefits to society. It seems that they have a very agricultural, anthropocentric view on nature even though this guidance is made to protect endangered species.
In the guidance for energy transmission infrastructure projects the listed impacts are through clearance of land and the removal of surface vegetation: the existing habitats may be altered, damaged, fragmented or destroyed and the indirect effects could be much more widespread especially when projects interfere with water and soil quality. Also when building the site there will be increased traffic, presence of people, noise, dust, pollution, artificial lighting and vibration and the risks of collision with power cables.
Electrocution can have a major impact on several bird species, and causing the death of thousands of birds annually.
There is a strong consensus that the risk posed to birds depends on the technical construction and detailed design of power facilities. In particular, electrocution risk is high with “badly engineered” medium voltage power poles (“killer poles”) (BirdLife International, 2007).
By acknowledging the loss of thousands of birds annually because of the energy infrastructure can we say that they are part of energy infrastructure?
