The Musician Wren or Organ Wren (Cyphorhinus arada) 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 or many other variants of this name, all based on the Tupi wirapu 'ru. 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. The Musician Wren is also believed to bring good luck, which leads some people to kill it in order to have it stuffed. Even though there are no reliable statistics of its numbers, the Musician Wren, due to its large range and being locally fairly common, is not considered threatened.
the song can be heard in the months of october to november when the bird builds its nest
