Subsequent time you’re in want of an odd animal truth to fill a conversational lull, contemplate the nesting preferences of the Humboldt penguin. To guard their eggs and hatchlings from solar, warmth and different parts, they dig nests and burrows out of the accrued guano (poop) of generations of Humboldt penguins and different sea birds.
Native to western South America, Humboldt penguins take their title from the Humboldt present that flows just a few miles offshore. They breed—and dig their poop nests—alongside a slim strip of coast from Foca Island in Peru to Guafo Island in Chile. The rocky coast and islands the place these temperate penguins stay don’t provide a lot safety from predators and the weather, particularly the warmth of the solar.
Which is the place the poop nests are available in. A tunnel, nest or burrow dug into guano makes a wonderful shelter, particularly for eggs and hatchlings.

Sadly, sea hen poop additionally makes a wonderful fertilizer and the mining of guano inside the penguin’s vary devastated Humboldt populations within the 19th and early 20th century.
At the moment, with the event of artificial and different fertilizers, guano mining isn’t the risk it as soon as was, however the legacy of guano mining stays. It may take a very long time for guano to turn into deep sufficient for nesting so many Humboldt’s are nonetheless compelled to construct their nests in no matter shelter they’ll discover, normally below rocky overhangs or in shallow caves.

Different challenges—like marine air pollution, artisanal and industrial fishing, and local weather change-driven change to the Humboldt present—are additionally taking their toll on Humboldt populations, and these penguins are as soon as once more thought-about a species at susceptible to extinction.
Flightless Birds in a Altering World
Like all penguins, Humboldts are flightless and tailored for a life within the sea, reasonably than the sky. They hunt within the chilly, nutrient-rich waters of the Humboldt Present, the world’s largest marine upwelling, that flows just a few miles offshore. They’re glorious swimmers and deep divers of their pursuit of anchovies and different fish.
Inside the Humboldt marine ecosystem, notes Angelo Aguilar, a fisheries specialist for TNC Peru’s Oceans program, “Humboldt penguins are essential to the stability of the entire ecosystem, each as predator and as prey for sea lions and sharks. Their dynamic place within the ecosystem contributes to the well being of the meals chain.”
Endemic to each Chile and Peru, Humboldts are medium-sized penguins and develop to between 66-70 centimeters (about 2 toes) and weigh between 4-5 kilograms (8-10 kilos). They attain sexual maturity at in regards to the age of three and, when meals and shelter are secure and plentiful, can stay to between 15-20 years. The males are usually bigger than the females.

They’re considered one of 4 species of “banded penguins,” named for the curving black band that runs throughout their chests. (The opposite banded penguin species are the Magellanic, African and Galapagos.)
Humboldt penguins expel warmth from their our bodies by small pink patches of naked pores and skin round their eyes and the bases of their payments. In scorching climate, they’ll appear to be sun-burned vacationers who stayed too lengthy within the solar. And whereas Humboldts are tailored to hotter temperatures, they’re extremely susceptible to local weather change.
For Humboldts and so many different species, life is all in regards to the Humboldt Present and the very important connection between the land and sea.
Assist for Humboldt Penguins in Peru
In Peru, it’s commonest to see Humboldt’s in protected pure areas like System of Guano Islands, Islets and Peninsulas Nationwide Reserve (Ballestas Island, San Juan capes) and Paracas Nationwide Reserve. Moreover, Illescas Nationwide Reserve is probably the most northern place in Peru the place Humboldt penguins will be discovered. Since 2022, TNC has been working with the Peruvian authorities to guage the feasibility of various marine conservation schemes to guard the biodiversity of Illescas. One of many emblematic species that would profit from these efforts is the Humboldt penguin, together with different species.
The Peruvian authorities has additionally moved to supply particular authorized protections for Humboldts by prohibiting their looking, possession, seize, transportation and export for business functions. At the moment, below the management of the Peruvian authorities, efforts have begun to develop a conservation plan to guard Humboldt penguins and sea otters, as they’re endangered, and their pure habitats are threatened.

Moreover, Peru’s Nationwide Service of Pure Protected Areas of the State (SERNANP) is chargeable for the administration of the protected pure areas the place the Humboldt penguin lives. The Ministry of the Setting (MINAM) is accountable for coordinating environmental and conservation insurance policies and works on the regulation and management of species trafficking.
On the science facet, says Aguilar, “The are totally different establishments that help and fund research to monitoring and assessing the inhabitants and ecology of the Humboldt penguin, which helps to develop simpler conservation methods.”
A Hopeful Future for Humboldts and the Humboldt Present
For greater than a decade, TNC has superior conservation of the enduring Humboldt Present. Along with its significance to animals like Humbolt penguins, this marine ecosystem can also be a lifeline for 1000’s of fishers and communities, enabling them to outlive and prosper.
In a collective effort with native communities in Ecuador, Peru and Chile, TNC helps safeguard marine biodiversity and promote the sustainable use of marine sources. As in all of TNC’s work, science is the inspiration for actions to advance the restoration and resilience of the Humboldt Present.
Utilizing instruments like FishPath, which allows sustainable fisheries in areas with restricted knowledge, alongside Digital Monitoring, TNC helps fisheries sectors of their efforts to scale back unreported and unregulated fishing, promote accountable fishing practices, and shield marine ecosystems.
In Peru, TNC works intently with SERNANP and artisanal fishing organizations to strengthen good practices in artisanal fishing inside marine-coastal protected pure areas, like Illescas Nationwide Reserve. These actions intention to particularly scale back the bycatch and incidental seize of Humboldts and different species.

On this regard, Aguilar stresses that the conservation of marine sources requires the joint and coordinated work of various establishments, particularly public-private partnerships, that enable for native community-based contributions. It’s essential that communities are concerned in all features, notes Aguilar, from fundamental analysis to the implementation of public coverage.
“The involvement of communities all through this course of,” he says, “is important to make sure the efficient compliance of such measures.”
Humboldt penguins have come again from the sting of extinction earlier than—it’s going to take the continued efforts of native communities, governments and companions to carry them again once more.
