Humboldt penguins are named after the cold Humboldt current which flows along the coast of North and South America.
These penguins are one of the most timid species of penguins.
Humboldts often get tangled in fishing nets, or their eggs get trampled by guano harvesters.
Humboldt penguins have a gland which enables them to drink salt water in addition to fresh water; the gland concentrates excess salt which then dribbles down the bill.
When food is scarce the parents feed only the larger chick and the smaller chick quickly starves.
