The cinnamon warbling finch (Poospiza ornata) is a species of bird in the family Thraupidae. It has mainly grayish upperparts, with a slate-gray head marked with a cinnamon crescent under the eye and supercilium, two white wingbars, and a chestnut patch across the center of the back. The underparts are largely cinnamon with a rufous breast and flanks. The average length is 13 cm (5.1 in) and the typical mass is around 12.5 g (0.44 oz).. The species is almost entirely found in the arid regions of Argentina, where it spends its breeding season. During the non-breeding season, it migrates to the north and east, possibly reaching as far as Uruguay, and tolerates more moist habitats.
Taxonomy
The cinnamon warbling finch was formally described in 1865 as Phrygilus ornatus by the German ornithologist Christian Ludwig Landbeck on the basis of a specimen from the "plain between the Portillo guard and the houses of Melocoton".[2] It was later transferred to the genus Poospiza. The name of the genus is derived from the Ancient Greek poas, meaning 'grass', and spiza, meaning 'finch'. The specific epithet comes from the Modern Latin ornatus, meaning 'ornate' or 'splendid'. It is most closely related to the Bolivian warbling finch. The species does not have any recognized subspecies.[3]
Description
A medium-sized Poospiza finch, the cinnamon warbling finch has an average length of 13 cm (5.1 in) and a typical mass of around 12.5 g (0.44 oz). The upperparts are largely grayish in color, with two white wingbars formed by the white apices to the greater and median coverts. The wing coverts are gray to brownish-gray, while the rectrices are largely brownish-gray with white outer retrices. There is a prominent chestnut patch across the center of the back. The face is slate-gray, with the crescent under the eye and the supercilium both cinnamon-brown. The chin and throat are also cinnamon, blending into the rufous breast and flanks, before turning cinnamon again on the abdomen. The legs are blackish and the bill is bicolored, black on the maxilla and silver-black on the mandible. Females are paler than males and juveniles have pale-seeming underparts heavily marked with gray.[3]
The cinnamon warbling finch is most similar to the rusty-browed warbling finch, which shares the extreme northern portion of the former's non-breeding range. However, the rusty-browed warbling finch prefers a different habitat, the Yungas, and has a rufous supercilium instead of a cinnamon one.[3]
Distribution and habitat
The cinnamon warbling finch is almost entirely endemic to Argentina, with some records from the Colonia Department of Uruguay that require further investigation, as they may represent escaped pets. During the breeding season, the finch is found in arid and semi-arid habitats in Argentina. During the non-breeding season, it migrates to the north and east, as far as Uruguay, and tolerates more moist environments. Its range is Argentina stretches from the provinces of Salta and Catamarca south to Neuquén, Río Negro, and Buenos Aires. Besides these migrations, the finch also moves locally in response to local environmental factors.[3]
