Uirapuru.

There is a bird in Brazil that sings only once a year, when it builds a nest, in order to attract a mate; even then, only from five to ten minutes early in the morning.

According to the legend, Uirapuru's song is so beautiful that all other birds stop singing to listen to it. Both in legend and reality Uirapuru is a symbol of rarefied beauty.

And loneliness.

Listen to the Uirapuru.
