Guadalupe fur seals (Arctocephalus townsendi) have established a second haul-out in the Gulf of California on El Farallón de San Ignacio Island, along the mainland coast of Mexico. Unlike the smaller, seasonal site first used in 2019–2020 on Las Ánimas Islet. Guadalupe fur seals appear to have been using El Farallón since 2014. In 2020 there were 492 fur seals present at El Farallón in January, and 771 in November—the majority of which were juveniles. The discovery of this new haul-out at El Farallón de San Ignacio Island brings the total number of sites where this species of fur seal is known to rest and breed to just four. With only a single breeding colony (rookery) on Guadalupe Island, Guadalupe fur seals remain vulnerable and may require additional protections in the southern Gulf of California to secure their future.
