The Safari Park is also a nesting site for white faced ibis, cattle egret, common gallinule and a few other water birds. It is also a favored site for a wood stork, which may be one of the only ones of its species in California at any given time.
In 2022 an extremely lost Stejneger's Petrel usually pelagic in the pacific ocean, breeding in Chile was found at the park and was the San Diego county record.
Currently a zone tailed hawk is residing around the park, and quite a few other rarer birds have been seen over the years such as warblers like the American redstart and neotropic cormorants.
The San Diego Zoo has some of the common mammals seen in the area, such as house mice which can sometimes be seen in some of the aviaries, fox squirrels, desert cottontails which I have seen around the hippo exhibit, brush rabbits, Botta's pocket gopher, raccoons and black rats. Green anoles and fence lizards can be pretty easily seen, house geckos or mourning geckos, not sure on the species as flat tail and Mediterranean have been reported, can be seen around the zoo and inside reptile house enclosures. Some other reptile species like california king snakes and southern alligator lizards have been reported on inaturalist as well. Many of the common birds in San Diego such as yellow warblers, rufous, Allen's, and Anna's hummingbirds, lesser goldfinch, song sparrows and many others can be seen. Introduced red-crowned amazons, Swinhoe's white-eye and scaly breasted munia can sometimes be seen.
Quite a few rare birds have been seen in the zoo, earlier this January and February 5 oriole species were seen at once in the entrance trees, orchard, hooded, Bullock's, Scott's, and Baltimore, 5 out of 6 species which have been spotted in California. Over the years worm-eating warbler, indigo bunting, rose breasted grosbeak, scarlet tanager, american redstart, blackpoll warbler and quite a few other rarities have been seen.
