Bird flu cripples US Caspian Tern colonies

Avian influenza (HPAI) has wiped out thousands of Caspian Terns on Lake Michigan this summer, according to the Wisconsin Department of Natural Resources.

Routine monitoring of islands around the Door Peninsula in Wisconsin in early June produced a horrific shock for ornithologists, who found no fewer than 1,476 dead adult terns strewn across several colonies. The death toll for Gravel Island and Hat Island combined was 1,221.
