New Zealand has the dubious distinction of being a popular place for whale beachings, with its history of such occurances dating back to 1840.  Pilot whales are the ones that this happens to most often, and scientists say this is because New Zealand is on the animals' migration route, but truthfully, these same scientists actually don't have any idea why whales beach themselves.  Now, for the second time in a month, pilot whales have wound up on the shore at Spirits Bay.  An 80 member pod of the creatures has been found there, and at least half of them have already died in spite of massive efforts to save them.  Last month, 58 pilot whales stranded themselves and only nine were saved.
