I remember hearing things like that from the assemblies. It's funny in about 1973 or 1974 strangely enough turkey vultures showed up here in this area of Canada. My father was totally convinced they were here to deal with the aftermath of Armageddon.
Turns out they were just another species that the government was reintroducing to the area. LOL They had been here for a long time until the settlers shot them all.
