Yungasguan

Bestimmung

Male and female Yungas guans are alike. They are chestnut above and dull reddish brown below. The belly has brown to orange horizontal markings and the tail is dark brown. The head and back of the neck are black. Feathers of the neck, back, and chest have white edges that are significantly larger than those of P. obscura. The bare skin of the face is slate gray and the wattle is red. <p>The Yungas guan is larger than P. obscura; the lengths of nine specimens were between 77.0 cm (30.3 in) and 89.0 cm (35.0 in) compared to 48.0 cm (18.9 in) and 66.0 cm (26.0 in) for two specimens of P. obscura.

Taxonomie

Prior to late 2020, the Yungas guan was considered a subspecies of dusky-legged guan (Penelope obscura). A 2018 publication detailed many morphological differences between them. An earlier publication had highlighted their very different vocalizations. Based on that evidence and the members' personal knowledge, the South American Classification Committee of the American Ornithological Society elevated it to species rank in December 2020, and the International Ornithological Congress followed suit in January 2021.

Verbreitung und Lebensraum

The Yungas guan is found on the east side of the Andes in the Southern Andean Yungas of southwestern Bolivia and northwestern Argentina. It inhabits subtropical evergreen forest from below 1,000 m (3,300 ft) up to approximately 1,900 m (6,200 ft).

Verhalten

Der Yungasguan frisst Früchte und Blätter; deren Anteile und die genutzten Pflanzenarten unterscheiden sich innerhalb seines Verbreitungsgebiets. Obwohl der Vogel überwiegend ortstreu ist, nimmt man an, dass er je nach Jahreszeit unterschiedliche Höhenlagen aufsucht. Die Brutzeit liegt hauptsächlich zwischen Oktober und Dezember.
