Rio Grande Chirping Frog

Rio Grande chirping frog, Eleutherodactylus cystignathoides

The Rio Grande chirping frog is a terrestrial frog that lays its eggs in moist soil and leaf litter. As complete metamorphosis occurs within the egg, they are extremely well adapted to the urban environment. The native range of these frogs is extreme south Texas along the lower Rio Grande Valley; however, populations have been unintentionally introduced in other parts of Texas as well as Louisiana and Mississippi through potted plant trade. Outside their natural environment, they are often found in crevices near buildings. During rainy weather, their loud call can often be heard in clusters.

Although mentioned twice in the past, the Rio Grande chirping frog remains one of my favorites.
