Moments with a Santa Cruz Island Fox, a once critically endangered species. With all of the weighty news on climate change and challenges that many species face, it is important to also celebrate the wins.
This species was down to fewer than 100 individuals at its lowest point, mainly due to predation from golden eagles. Historically, golden eagles were not known to breed on these islands. Bald eagles, which primarily feed on fish, had claimed the territory; however, after DDT contamination wiped out the local bald eagle population, golden eagles moved in, drawn by feral pigs left over from the island's ranching days. It didn't take long before they began targeting the foxes as well.
In an extremely successful recovery effort, pigs were removed, golden eagles relocated, and bald eagles were reintroduced - back to reclaim their territory. Human-driven impact being reversed through targeted and balanced action. Santa Cruz Island foxes have had one of the fastest recoveries of any mammal under the Endangered Species Act, and this little guy is proof it's still paying off.
