“Isla Todos Santos—The Todos Santos Islands are two islands (31 and 87 ha). The endemic species of woodrat (Neotoma anthonyi) is extinct from the south island due to predation from feral cats (Mellink, 1992; Donlan et al., 2000). The woodrat has not been reported from the north island. The endemic Todos Santos Island deermouse (P. m. dubius) is listed as threatened, but is abundant on both islands (Mellink, 1992; Donlan et al., 2000; C. J. Donaln, unpublished data). Cats were introduced to theislands sometime between 1910 and 1923 (Howell, 1912; van Denburgh, 1924) and European rabbits in the 1970s (Donlan et al., 2000). Cats and rabbits were removed from the south and north islands in 1997 and 2000, respectively (Wood et al., 2002). Donkeys from the north island were translocated to the mainland (Carrion et al., 2007).”
Mammals:
- Deer Mouse (Peromyscus maniculatus dubius)
- Bryant's Woodrat (Neotoma bryanti anthonyi)
- Harbor Seal (Phoca vitulina)
Reptiles:
- Southern California Legless Lizard (Anniella stebbinsi)
- Side-blotched Lizard (Uta stansburiana)
- Western Fence Lizard (Sceloporus occidentalis)
- Western Skink (Plestiodon skiltonianus)
- Garden Slender Slamander (Batrachoseps major)
"...the nest of a Bald Eagle was found on the top of a rocky pinnacle just off the northern end of the larger islet. Fifty species of birds have been observed on the Todos Santos Islands, most of them of sporadic occurrence, but Western Gulls and Cormorants breed there." (Nelson. E. W. National Academy of Sciences. First Memoir. Lower California and its Natural Resources. XVI:86)
