Open ocean and coastal waters. Breeds in dense colonies on steep rocky islands and sea stacks.
Song & Call Comparison

A rising, chattering 'budgerigar' chatter: rapid series of 'chek-chek-chek' and melodic warbling. Enormous wild flocks produce a continuous roaring chorus. Good vocal mimics in captivity.
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
虎皮鸚鵡
The budgerigar is the third most popular pet in the world after dogs and cats, and by far the most common pet parrot. Wild budgies travel in enormous nomadic flocks that can darken the sky. Males can learn to mimic human speech, with one record-holding budgie having a vocabulary of 1,728 words.
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.
