Have any of you noticed a decline in your bull frogs in the last ten years. I have 6 small lakes and ponds in hearing distance of my house and years ago they would be so loud it would be hard to talk setting on the porch at night. Now you might hear one or two sometimes none. On the river I hear a few at times but nothing like it use to be. Some people say frogs are the bottom of the food chain and they are the first effected by pollution. Insecticides get in the water and insects are the frogs main diet.
