Confirm with a PhotoAppearance
The Humboldt Penguin is characterised by its black back and white front, with a distinctive black band across the chest. Its face, bill, and feet have pink patches of bare skin that help regulate body temperature. The penguin's body is streamlined for efficient swimming.
Juveniles resemble adults but have greyer plumage and lack the defined chest band. There is no significant difference between male and female appearances, making visual sex determination challenging.

Attributes
Understanding Attributes
Rated 0–100 based on research and observation. A score of 50 is average across all bird species. These attributes are relative and don't necessarily indicate superiority.
Habitat & Distribution
Humboldt Penguins inhabit the coastal areas of Peru and Chile along the cold Humboldt Current. They prefer rocky shores and offshore islands with caves and crevices for nesting. These penguins are also found on some beaches with suitable breeding conditions.
While their range is limited to South America, some Humboldt Penguins can be seen in zoos and aquariums worldwide as part of conservation and education programs.
Distribution
Diet
Humboldt Penguins primarily feed on small schooling fish such as anchovies, sardines, and herring. They also consume squid and crustaceans.
These penguins are pursuit divers, chasing prey underwater and catching it with their sharp, hook-tipped beaks. They can dive up to 150 meters deep in search of food.
Behaviour
Humboldt Penguins are social birds, often seen in large colonies. They are excellent swimmers, using their wings as flippers to 'fly' underwater at speeds up to 30 km/h. On land, they waddle upright or slide on their bellies.
These penguins are known for their head-swinging displays during courtship and territorial disputes.
Calls & Sounds
Humboldt Penguins produce a variety of vocalisations. Their most common call is a loud, braying sound, often described as a donkey-like 'haw-he, haw-he'.
During courtship, they use softer, more melodious calls. Chicks emit high-pitched peeping sounds to beg for food from their parents.
Nesting & Breeding
Humboldt Penguins form monogamous pairs and breed year-round, with peak activity between March and December. Courtship involves vocalisations, head-swinging displays, and mutual preening.
Nests are built in burrows, caves, or crevices in rocky areas lined with guano and feathers. Females typically lay two eggs per clutch. The eggs are white and slightly larger than chicken eggs.
Both parents take turns incubating the eggs for about 40-42 days. Chicks are cared for by both parents for about 10 weeks before fledging. They reach sexual maturity at around 2-3 years of age.
Conservation
Humboldt Penguins face threats from overfishing, which reduces their food supply, and entanglement in fishing nets. Climate change and El Niño events disrupt their breeding patterns.
Conservation efforts focus on protecting breeding sites, regulating fisheries, and establishing marine protected areas to safeguard their habitat and food sources.

Additional Details
- Predators:
- Main predators include sea lions, sharks, and orcas in the water, while on land, they face threats from foxes, dogs, and birds of prey targeting eggs and chicks.
Birdwatching Tips
- Look for Humboldt Penguins along rocky coastlines in Peru and Chile
- Observe their distinctive swimming and diving behaviours from coastal viewpoints
- Visit protected areas like Punta San Juan in Peru for guaranteed sightings
- Bring binoculars to spot their unique facial markings
- Join guided tours to responsibly view nesting colonies
Did You Know?
- Humboldt Penguins can drink seawater thanks to special glands that filter out excess salt.
- They can hold their breath for up to 2.5 minutes during deep dives.
- These penguins moult all their feathers at once, staying on land for about two weeks during this process.
- Fishermen caught a Humboldt Penguin in a net in 2002 in Alaska. The most likely explanation for this extremely rare sighting is that the penguin hitched a ride with the fishing boat, ending up in Alaska. Although they theoretically may be able to live there, there have only been a handful of sightings.
