The monster tsunami that swept over Japan almost two weeks ago and killed thousands of people also took the lives of what U.S. Fish and Wildlife officials now estimate to be 110,000 Laysan and black-footed albatross chicks and 2,000 adult birds at Hawaii鈥檚 . On a happier note, biologists there yesterday reported that the albatross called Wisdom, often considered the oldest wild bird on record and who had been missing, returned to her nest.

The tsunami, coupled with two severe winter storms in January and February, killed off approximately 22 percent of this year鈥檚 albatross population.
