Mild December confuses Finnish birdlife

Finland's exceptionally warm December has confused migratory birds on their way south for the winter and encouraged other birds to sing and mate as if it were spring, experts said.

"Some of them (migratory birds) did not even leave because early winter was so warm and probably some of them first went south and came back," Lauri Haenninen, spokesman for environmental group Birdlife Finland, told AFP on Friday.
