This bird seems to have garnered considerable interest despite being an escaped cage bird.
Northern Red Bishop is native to northern tropical Africa, but has introduced populations in southern California, Texas, Florida, Puerto Rico, and a few smaller Caribbean islands. In California they are resident in coastal Los Angeles and Orange Counties mostly along the Los Angeles, San Gabriel and Santa Ana Rivers and along San Diego Creek. Elsewhere in California occasional escapes have been noted. Closer to home, small numbers have occurred irregularly in Santa Clara County where they have nested occasionally but no self-sustaining population has become established there. In San Francisco there have been occasional sightings in the past. Over the years I've seen single birds at Land's End and Lake Merced
Despite these sightings, this species is not currently accepted on the California bird checklist because it does not meet the criteria for a successful established introduction. Nonetheless it is on the "Watch List" of species which might be added in the future if their numbers increase and more self-sustaining populations are documented.
