Invest in the nest
The wild African penguin population has fallen by more than 97 percent in the past century.
“It’s thought there used to be over a million breeding pairs, and now there are only 25,000,” Aimee says.
One factor is overfishing, which has left Africa’s only penguins with less food. Climate change may also be playing a role, she says, because, “Warmer waters cause what fish there are to move elsewhere, out of the penguins’ (swimming) range.”
They are vulnerable to other threats, too. A single oil spill along South Africa’s coast has the potential to affect thousands of penguins, Aimee says.
The Aquarium took part in last year’s Invest in the Nest campaign to address one major challenge to the penguins’ recovery: a lack of appropriate, safe nesting areas where they can lay their eggs and rear their chicks.
The campaign generated funds to deploy artificial nest boxes as replacements for burrows the penguins dug in the mountains of guano on their historic nesting grounds. Strange as it sounds, the birds depended on guano left behind by generations of their predecessors to successfully rear their chicks, Aimee says.
“If you can picture the ground just covered in layers and layers of bird poop, the penguins would burrow into it as a kind of shelter, to provide protection against rain and heat,” she says. “In its absence, with bare rock left behind, nests overheat and flood.”
The campaign, launched by the Association of Zoos and Aquariums (AZA), raised close to $200,000 on Kickstarter. Donors could earn rewards for their contributions—including a “penguin party” with the birds in Monterey.
With the funds, SANCCOB is placing 2,000 artificial nest boxes on beaches in South Africa and Namibia.
