Populations are also found in montane and highland environments at higher elevations.

Cliff Chirping Frog

The Cliff Chirping Frog, Syrrhophus marnockii (also known as Eleutherodactylus marnockii), is a small terrestrial frog in the family Eleutherodactylidae native to the Edwards Plateau and adjacent areas of central Texas in the United States and northern Mexico. This tiny frog, typically only 2–3 cm in length, is adapted to rocky limestone terrain, hiding in crevices, under rocks, and in the thin soil pockets on cliff faces, rocky outcrops, and canyon walls. The species is named for its high-pitched, insect-like chirping calls produced by males, particularly on humid nights following rainfall. Unlike many frogs, the Cliff Chirping Frog undergoes direct development: eggs are laid in moist rock crevices and develop directly into miniature froglets without a free-living aquatic larval stage, eliminating dependence on standing water for reproduction. Diet consists of small arthropods, insects, and other invertebrates encountered in rocky microhabitats. The species is cryptic and rarely seen but can be abundant in suitable habitat on the Edwards Plateau, an area of karst limestone geography. It is currently assessed as Least Concern by IUCN, with populations considered stable across its rocky limestone range.
