The Earth’s magnetic north pole in 2011 is drifting toward Russia at a rate of 40-some miles per year, Tampa’s airport had to close down and change signage to be in order with the shifting north pole. This was required to keep aircraft pilots’ navigation compass readings on point. It is thought that the last magnetic polar shift that flipped north and south magnetic fields occurred 500, 000 to 780,000 years ago (according to the information at the above link). This could confuse birds in flight or as they awakened and were dislodged from trees where they slept by some incident either natural or man-made.
Scientists are examining the bodies of all the groups of dead animals to determine cause of death. In Italy, the turtle doves might have been poisoned by sunflower seed overeating at the sunflower oil factory. The Folly Beach SC fish (Menhaden fish, which are used for bait) may have died of hypothermia. A full report on all sites will be intriguing.
