Excerpt from Birds of La Plata, Vol. 2 Besides the little creaking chirp uttered at short intervals while flying or hovering, this Species has a set song, composed of five or six tenuous and squeak ing notes, uttered in rapid succession when the bird is perched. It is a song like that of the European Goldcrest in shape, and resembles it in sound, but is less musical, or more squeaky.
