Plains zebras aren’t native California wildlife, so these reports most likely come from zoos, safari parks, ranches, or other managed collections. Observations around the Sierra Nevada, Los Padres, and Central Valley are too scattered to imply a free-ranging distribution; each needs its local setting checked before interpretation.
Reports are spread fairly evenly across the year, with January, February, and December slightly higher and April notably lower. That pattern fits animals visible in managed settings rather than a California migration. It records when people submitted observations, not the size or status of any captive group.
