Wildlife near Riverside, CA

Illustrated wildlife of Riverside

Riverside sits inland in the dry basin below Box Springs Mountain, where citrus country meets the desert edge. Anna’s hummingbirds and California towhees hold the yards, western fence lizards and ground squirrels work the sun, and the Santa Ana River bottom draws herons and the occasional bobcat. Up on the surrounding slopes it is coastal sage scrub with roadrunners, coyotes, and red-tailed hawks riding the afternoon wind.

Built from recent research-grade iNaturalist observations. Identifications are community-sourced and may occasionally be wrong, and the ranking reflects where people record and photograph wildlife, so a species seen often here is not necessarily rare elsewhere. Some plants and animals are only out in certain seasons. Treat this as a lively snapshot of what people are finding, not a formal checklist.
