Humboldt Penguin vs Magellanic Penguin

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.

Magellanic Penguin

Spheniscus magellanicus

Huge4.1 kgMarine

Magellanic penguins are medium-sized penguins which grow to be 61–76 cm (24–30 in) tall and weigh between 2.7 and 6.5 kg (6.0 and 14.3 lb). The males are larger than the females, and the weight of both drops while the parents raise their young. Adults have black backs and white abdomens. There are two black bands between the head and the breast, with the lower band shaped in an inverted horseshoe. The head is black with a broad white border that runs from behind the eye, around the black ear-coverts and chin, and joins at the throat.
