Range and Decline
This bird was native to north Argentina, south Paraguay, north-east Uruguay and Brazil. It became rare during the 19th century due to trapping and loss of habitat, and only two possible reports of wild birds were received in the 20th century. Expeditions by ornithologists to southwestern Paraguay during the 1990s failed to turn up any evidence that the bird was still in existence. Furthermore, only the oldest residents of the region had knowledge of the macaw, with the species last recorded in the 1870s. It is most probable that the bird's disappearance is linked to the wholesale felling of the Yatay Palm, Butia yatay, whose nuts appear to have constituted its main food. However, suitable habitat remains in El Palmar National Park in the Argentine province of Entre Ríos as well as southern Brazil, however, no rumours of the bird's continued existence in the past several decades have been proven credible.

of song
I hadn’t known.”
—Hilda Doolittle (1886–1961)
“The variables of quantification, ‘something,’ ‘nothing,’ ‘everything,’ range over our whole ontology, whatever it may be; and we are convicted of a particular ontological presupposition if, and only if, the alleged presuppositum has to be reckoned among the entities over which our variables range in order to render one of our affirmations true.”
—Willard Van Orman Quine (b. 1908)
“Considered physiologically, everything ugly weakens and saddens man. It reminds him of decay, danger, impotence; it actually reduces his strength. The effect of ugliness can be measured with a dynamometer. Whenever anyone feels depressed, he senses the proximity of something “ugly.” His feeling of power, his will to power, his courage, his pride—they decline with ugliness, they rise with beauty.”
—Friedrich Nietzsche (1844–1900)
