Lowland tropical bullfrog
This frog has many young ones when there is a lot of rain.  It has the most in December.  The male frog digs a small hole in the ground called a burrow.  He sings for the females on the ground.  The female frog lays about 10 eggs in the burrow, covered in foam.  The tadpoles live in this foam nest and not in a pond or stream.
