Musician Wren

The Musician Wren is a species of wren named for its elaborate song. It is native to the Amazon Rainforest in South America, and west and southwestwards into the Amazonian Andes. In Portuguese it is known as Uirapuru.
Especially in Brazil, the Musician Wren is the subject of several legends and fables, most relating to its loud and beautiful song. One of these tells that when it starts singing all other birds stop their song to hear it.
