This species is not uncommon in the woods along the shores of the Plata,
and may be easily known to any person penetrating them by its loud
"cheerful soliloquy," for that phrase of Mr. Barrows, the North-American
writer on birds, well describes the artless, light-hearted song which it
utters at intervals while it roams about in the deep foliage, and which
reminds one of the careless whistling of a boy, whistling merely to
express his gaiety, but without having any particular tune in his mind.
It is migratory, and extends its range south of Buenos Ayres.
