Hmm… this story appeared on one of my CCD RSS feeds this morning:
Excerpts (my emphasis in bold):
From all appearances, the birds are starving to death. But no one can say exactly why. “Some feel it’s a natural phenomenon,” Watson says, but he has doubts. “I think the thing that has caused some of us to question this is that it appears to be occurring more frequently.”
They may have lacked food when they were being raised as chicks, he says, or just after they left the nest. He speculates that the timing of food availability could have been off, or that the young birds may have missed the feeding locations, en route.
Whenever I hear stories like this, e.g. bees not finding their way back to the hive, birds not finding feeding grounds along the migration path, my thoughts always come back to navigation and the impact that electromagnetic radiation can have on it.
It is undeniable that both bees and many birds use magnetic fields for navigational purposes. It is also undeniable that wireless internet devices, e.g. Wi-Fi routers, data intensive cell phones, iPhone, etc., have greatly increased in popularity. Not only is the proliferation of wireless devices of concern, but it my opinion, the frequencies of that radiation is different than it has been historically. There is a lot more electromagnetic noise in the frequency range greater than 1 GHz these days. For example, Wi-Fi, WiBRO, and WiMAX operate at 2.5 GHz (the same as your microwave oven).
