I keep hearing that frogs are “canaries in the mine”, their decrease in numbers warning of imminent environmental catastrophe. So it was with interest, and I confess, some amusement, when I read about the invasion of American Bullfrogs into British Columbia.
Wayne Campbell, former chief ornithologist of B.C. and the author of numerous bird books, said he went to investigate the stories of the Cranberry Lake bullfrogs a few springs ago, and was shocked by what he found.
“There was a big bullfrog floating on the surface, dead. Turns out it had choked, trying to swallow a gosling.”
“A small duck doesn’t stand a hope in hell. They are like alligators. I’ll tell you, boy, don’t put your fingers over the side of the boat.”
