Its popular name in Portuguese comes from the sound it makes, which remembers someone winding a watch. It is a little bird and very active. The couple built a hanging nest in a bag shape, with a side entrance. It is a very beautiful nest! In the first picture below they were just beginning the work, the nest was only about 10 cm tall. At the end it reaches more or less 40 cm.
