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.
Eurasian Wren
Extraordinarily loud for its tiny size: a rapid, powerful stream of trills, buzzes, and churring phrases. One of Europe's loudest songs by volume relative to body weight.

About These Birds
Budgerigar
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.
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
