King Penguin
Uses individually unique complex calls for mate and chick recognition in noisy colonies. Produces a loud, musical trumpeting. Chick whistles are distinctive per family unit.
Northern Gannet
Loud, harsh 'urrah-urrah' grunting and croaking at breeding colonies on sea stacks. Also gives a softer 'karrr' in flight. Large colonies are extremely noisy during the breeding season.

About These Birds
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
