How to recognise it
The Galapagos Penguin is the second smallest penguin species, characterised by its black upperparts and white underparts. It has a distinctive white band that runs from behind the eye, around the black ear coverts and chin, to join the white of the throat.
Both sexes look similar, with juveniles having a darker, more bluish-grey plumage. During the breeding season, adults develop a mottled appearance on their formerly white front due to moulting.

Its song and calls
Galapagos Penguins have a variety of vocalisations. Their most common call is a loud, braying 'hee-haw' sound, similar to a donkey's bray.
During courtship, they produce softer, more musical whistles and trills. When alarmed, they emit sharp, staccato barks.

Tips for seeing it
- Look for them along the rocky shores of the Galapagos Islands, especially on Isabela and Fernandina.
- Best observed during early morning or late afternoon when they're most active.
- Watch for their distinctive diving behaviour near the shore.
- Join a guided tour for the best chances of spotting these rare penguins.
What it eats
Galapagos Penguins primarily feed on small schooling fish such as anchovies, sardines, and mullet. They are opportunistic feeders, also consuming squid and crustaceans.
These penguins typically forage in shallow coastal waters, diving to depths of up to 30 meters to catch their prey.
Nesting and breeding
Galapagos Penguins form monogamous pairs and can breed year-round, though peak breeding occurs when marine food is abundant. Courtship involves mutual preening and vocalisations.
Nests are built in sheltered locations such as lava tubes, caves, or crevices in rocks. The female typically lays two eggs, though often only one chick survives.
Both parents share incubation duties for about 38-40 days. After hatching, chicks are guarded for about 30 days and fledge at around 7-8 weeks old, though parents continue to feed them for several more weeks.
Behaviour
Galapagos Penguins are excellent swimmers. When hunting, they use their flippers to 'fly' underwater at speeds up to 35 km/h. On land, they waddle upright or hop over rocks.
These penguins are social, often seen in small groups, and engage in mutual preening to strengthen bonds.
Conservation
The Galapagos Penguin is classified as Endangered due to its small population and limited range. Major threats include climate change, which affects food availability, and introduced predators.
Conservation efforts focus on habitat protection, predator control, and monitoring population trends.
