Try closing your eyes. The Howler Monkey sounds like a cross between a donkey and a dog. To sound-off the same way, blow across the tops of empty bottles. Damselfish make a chirping sound. Beat lightly on the can drums to make a similar sound.
Grasshoppers have bumpy legs and stiff wings.
They rub a leg on the edge of a wing to sound-off. Try to make a grasshopper sound by running a playing card along the teeth of the comb in a steady rhythm. Try one or more cards at a time. Male Cicadas are the loudest insects. They have a platelike organ called a tymbal.
