One in five Australian birds and mammals are facing a "high to extreme risk" from the escalating bird flu virus that's starting to devastate wildlife. This includes 13 critically endangered and 70 endangered species or subspecies rated as at extreme, very high or high risk. The Christmas Island frigatebird, little penguin, and Australia sea lion are among the species listed that face high or extreme risk. "This is a shocking list which reveals the confronting extent of the potential disaster facing Australian wildlife," Invasive Species Council chief executive Jack Gough said. While no cases of bird flu have yet been detected in Australian poultry, losses worldwide have been placed at 140 million birds.
