These popular penguins have faced a lot of threats in recent years that have put them on a dangerous path.

Species name: African penguin (Spheniscus demersus), a.k.a. the black-footed penguin or the "jackass" penguin for its donkey-like braying sounds. (The nickname has nothing to do with the penguin's personality.)

Where found: Coastal southwest Africa, including South Africa and Namibia and the Penguin Islands, which as you might guess were named after their black-and-white denizens.

IUCN Red List status:Endangered. Previously listed as "vulnerable to extinction," they were upgraded to "endangered" in 2010 due to a rapid population decline of nearly 70% over the past decade.

Primary threat: Lack of food, primarily due to commercial fishing, has been the driving cause for the African penguin's decline. In addition some fish species have shifted their habitat further west, putting them out of the penguins' range. Beyond food supplies a number of other factors have affected penguin survival, including oil spills, human disturbance of rocky nesting sites or egg collection, invasive cats, diseases and competition with other species. In other words, it's kind of tough to be an African penguin these days.

Previous Extinction Countdown articles about this species: The most notable articles covered the strange saga of the supposedly gay penguins brought to Toronto Zoo in 2011. It turned out they were just friends. Going back to 2010, I wrote about a type of facial recognition software that could be used to identify individual penguins and help to monitor their populations.

Notable conservation programs: SANCCOB (the Southern African Foundation for the Conservation of Coastal Birds) helps rehabilitate penguins and other seabirds that have been caught in oil spills and conducts research into seabird diseases. BirdLife South Africa does great work in the region on a lot of different fronts. A number of zoos have ongoing breeding programs (Tampa Zoo hatched a chick in August, and Maryland Zoo celebrated four hatchlings in September and October).

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
