So its been quite a problem for a while now but Cerulean Warblers are in a precipitous decline. Apparently, the populations have dropped 82% in 40 years which is pretty dismal but to make matters worse, the U.S. Fish and Wildlife Service has decided not to list it as endangered. The National Audubon Society may follow up on this decision and fight it but it is very depressing when a bird can decline this rapidly and be ignored by the Endangered Species Act.
