Rio Grande Leopard Frog

The species is primarily aquatic, and mostly nocturnal, though they can be often found during the day resting along the edge of the water. Despite their geographic range being mostly arid or semiarid, they inhabit permanent water sources, such as streams, creeks, and ponds. They are insectivorous, but like most frogs, will eat almost anything they can overpower and swallow. Mating occurs during the rainy periods of the spring and fall. The males make a rattling call which is loud enough to be heard a quarter mile or more away. Eggs are laid in large masses attached to aquatic vegetation. — Wikipedia
