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.
Rock Pigeon
Soft, rhythmic cooing 'roo-c'too-coo' repeated multiple times, with emphasis on second syllable. Male courtship coo is deeper and more persistent. Wing-clapping on takeoff is loud.

About These Birds
periquito-australiano
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.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
