Galapagos Penguin vs Humboldt Penguin

Galapagos Penguin

Spheniscus mendiculus

Huge1.9 kgMarine

The average Galápagos penguin is 48–50 centimetres (19–20 in) tall and weighs around 2–4 kilograms (4.4–8.8 lb). It is the second-smallest species of penguin, after the little penguin. Females are usually smaller than males. Galápagos penguins have a black head with a white border running from behind the eye, around the black ear coverts and chin, to join on the throat. The top of the beaks are black and fade into pink on the bottom. They have two black bands across the breast that connect to the back, the lower band extending down the flanks to the thigh.

Humboldt Penguin

Spheniscus humboldti

Huge4.4 kgMarine

Humboldt penguins are medium-sized penguins, growing to 56–70 cm (22–28 in) long and a weight of 2.9 to 6 kg (6.4 to 13.2 lb). The sex of the Humboldt penguin cannot be recognised via differences in plumage, as they are monomorphic. The male is heavier and larger than the females. Their sex can be determined via head width and bill length; the male has a longer bill than the female. While all the Spheniscus penguins are close to each other in size, the Humboldt penguin is the heaviest species in the genus, with 123 females weighing 4.05 kg (8.9 lb) on average and 165 males averaging 4. Voice: The Humboldt penguin has different calls that it uses to communicate in different ways. The function of its calls are consistent among Spheniscus species. If an individual comes too close to an adult Humboldt penguin, the Yell is a warning call which is followed by pecking or chasing if ignored.
