Aussie Bird Flies a Long Way

An Australian bird has flown a long way. Scientists were studying birds on the shores of western Alaska in the Arctic. They saw a bartailed godwit and examined the bird believing it to be a local inhabitant. The tag on its leg, however, showed that it had flown a very long way. Australian scientists had banded the bird earlier in Victoria. The small creature had travelled more than 8,000 miles.

Studies had shown that bartailed godwits usually spend their life in the same local area where they were born, though many presumed that they flew to the Arctic to breed. This has now been substantiated by the discovery. It is known that banded dunlin and semipalmated sandpipers fly to the Arctic from Asia and South America.

With the Arctic thawing, damage could be done to future breeding populations of birds. The hotter Arctic summer could affect the survival of the young. Migratory shorebirds are decreasing in number. This is due, it is believed, to habitat loss and global warming. More research is required in order to identify specific causes.

Strange Events Continue Around the World

Raising the ire of scientists, mysteries continue to happen. A year ago people in Arkansas experienced an omen for the new year. Thousands of redwing blackbirds fell from the sky, dead. Investigators came to the odd conclusion that fireworks scared them to death. Apparently they flew around blindly in the night, crashing into the walls of buildings.

In Altona, Germany, a large number of toads were found dead in a strange way. They had holes in their backs and their livers had been removed. It was concluded that crows had developed a way of getting at the nutritious livers without consuming poison from the toads. Taking the "myth" a little further "experts" said with livers removed the toads' lungs had inflated causing them to explode. Darn clever these scientists. They always have an answer.

They do seem to get some things right, however. In Alaska 55 musk oxen were frozen to death despite having two layers of fur. A tidal surge followed a storm at sea which cracked the frozen ice and the oxen fell into the freezing ocean. Surface sea water later refroze around the dead animals.

Odd events continue around the world with seabirds washing up dead on California beaches and swarms of ladybirds in Colorado.
