As you travel through this area, you will undoubtedly encounter one or more species of terrestrial vertebrates residing here. The following lists contain 10 species of amphibians, and 20 species of reptiles which have been reported in the area. Many of these animals are rare or extremely inconspicuous so your chances of seeing them are slim.
Some are often heard but not seen and these are the toads and frogs. The timing of their chorusing during courtship is as predictable as the arrival of certain species of birds. If you are out watching cranes or waterfowl on a warm day in late March or early April, you will hear western chorus frogs, a tiny treefrog about an inch in size with a voice that sounds similar to that produced by running your fingernail along the teeth of a plastic comb. I have heard them as early as March 5 but more commonly around March 21-25. The plains spadefoot toad breeds from early May through August and is stimulated by rainfall. Their call can be confused with a calf bawling. The earliest I've heard them is April 22. The guttural clucking of southern leopard frogs begins in mid-April while the first trilling of rocky mountain toads is usually in early May. A true sound of summer is the low "jug-o'rum" call of the bullfrog. Late May through July is when this species is heard. Being able to recognize the voices of these "lowly" inhabitants simply adds to the enjoyment of being out in the field on any spring day.
