Baja California chorus frog
species of amphibian
The Baja California chorus frog (Pseudacris hypochondriaca) is a cathemeral species of treefrog of Western North America. It was formerly considered as a population of the Pacific chorus frog (Pseudacris regilla), but was split and raised to species status in 2006. The species ranges on the west coast of the North America from Baja California through southern California. Individuals live from sea level to more than 10,000 feet in many types of habitats, reproducing in aquatic settings.
Description
The Baja California chorus frog can grow .75 - 2 inches long from snout to vent (1.9 - 5.1 cm).
It has a dark stripe that extends from its nostrils through the eyes to shoulders. It can be a variety of colors, including green, tan, brown, gray, reddish, and cream, and has the ability to change color in response to environmental conditions. The dark stripe does not change color, but the body color and markings can change hue, chroma, and lightness to aide with camouflage. The belly is pale with yellow underneath the legs. There is also a Y-shaped or triangular marking between the eyes, a common feature in chorus frogs.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Baja California chorus frog”, the useful work is to connect “species of amphibian” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Apr 17, 2026. The linked authority identifier is Q4680143. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2006.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
