How Cell Phones are Killing Birds
January 15, 2008
Migratory birds are known to use the geomagnetic field as a source of compass information. Scientists have shown that oscillating magnetic fields disrupt the orientation behavior of migratory birds.
Researchers found that robins were disoriented when exposed to a vertically aligned, broadband or a single-frequency field.
According to Alasdair Philips of Powerwatch,
"... medium- and short-wave frequencies have been used since the 1930s with little evidence of any effect on bird behavior. But since the mobile phone networks went up there have been increasing reports of birds, especially homing pigeons, getting lost. Research now needs to look at the effects of base station signals, particularly in view of the disorientating effects of EMR ‘noise‘ reported in this study."
