It is monotypic in the genus Pipraeidea. It occurs in the Andes of northwestern Argentina, Bolivia, Colombia, Ecuador, Peru and Venezuela, as well as in the highlands of northeastern Argentina, south Brazil, Paraguay and Uruguay. TaxonomyThe fawn-breasted tanager was described in 1819 by the French ornithologist Louis Jean Pierre Vieillot from a specimen obtained in Brazil. He coined the binomial name Tangara melanonota.[2] The specific name melanonota is from the Ancient Greek melas "black" and nōtos "back".[3] The current genus Pipraeidea was introduced by the English naturalist William John Swainson in 1827.[4] The name combines the genus Pipra which had been introduced by Carl Linnaeus in 1764 with the Ancient Greek eidos meaning "form" or "likeness".[5] Recent DNA evidence places this species as closely related probable relation to the blue-and-yellow tanager.[3] Two subspecies are currently recognized:[6]
DescriptionThe fawn-breasted tanager has an average body length of {{cvt|14|cm}} and can weigh {{cvt|18|-|25|g}}. This species of tanager has an unusually short, wide beak, similar to the beaks of swallows, as well as short legs and tail, and long wings.[7] The most noticeable coloration of this species is its sky-blue crown and broad black mask that extends over the eyes into ear-coverts.[8] The coloration of male crown and nape is a medium blue, and the forehead, lores, ocular area and ear-coverts are deep black. The mantle and back of males are a dull blue color, the lower back and rump a bright turquoise-blue, tail dusky blue, throat and the underparts of the body are a cinnamon color. The iris is a dark red to reddish-brown color, and the bill is dusky with a lower mandible that is normally grey.[9] The female has a similar coloration but is usually duller, particularly in the crown region, and with a brownish coloration on the back. Juveniles are almost without pattern and have a dull brownish-grey coloring.[7] The fawn-breasted tanager is usually seen singly or in pairs, most often in the semi-open, but it may perch at any height.[8] Calls consist of "see" or "swee" tones varying in sets of 4 or 5 notes sung slowly, or a higher number of notes, around a dozen, uttered in a pulsating trill pattern in a faster rhythm.[7][10] Habitat and distributionThe range of the fawn-breasted tanager extends throughout South America, covering most of Brazil, Venezuela, Colombia, Peru, Ecuador, Bolivia, east Paraguay, Uruguay, Northeastern Argentina, following towards the southern bank of the Río de la Plata. The species can be found in habitats along forest borders, bushy pastures, and cultivated small semi open areas with large trees and clearings with scattered trees. The elevation range that this species can tolerate varies geographically. In the Andes and Ecuador it can be found at altitudes of 1500–2500 m, with a maximum of 3000 m. In Colombia, it occurs down to 900 m, and in Venezuela to 400 m.[7] DietThe species has a mixed diet which includes vegetable matter such as berries, fruit pulp, buds, flowers and seeds, as well as insects such as moths, butterflies or larvae. It may form part of mixed species flocks and has been known to congregate at fruiting trees with other birds, but generally feeds alone.[7] Movement and breedingThe fawn-breasted tanager engages in seasonal migration. It can be found in northern Venezuela during the months of January through June, the presumed breeding period for this species. It is present in Pacific Colombia during November through March. The populations located in southern regions, such as those located in Southern Argentina may migrate to more northern localities during the coldest months.[7] The species constructs well-lined cup-shaped nests, composed of moss, sticks, grass, straw fragments, and colored threads, in forest borders on the edge of pine branches, {{cvt|15|–|20|m}} from the ground. The nests are concealed with epiphytes and mosses. Information on specific breeding patterns is limited, but it is known that females lay 2-3 eggs and incubate them for 12–14 days, and that nestlings remain in the nest for 18–22 days.[11] ConservationThe species is currently classified as Least Concern by the IUCN due to its extremely large range, variety of habitats and apparently large population size.[1] Due to opening of forested areas through agriculture and other anthropogenic changes, it may be expanding its range locally.[7] References1. ^1 {{IUCN|id=22722691 |title=Pipraeidea melanonota |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} {{Taxonbar|from=Q384702}}{{DEFAULTSORT:tanager, fawn-breasted}}2. ^{{ cite book | last=Vieillot | first=Louis Jean Pierre | author-link=Louis Jean Pierre Vieillot | year=1819 | title=Nouveau dictionnaire d'histoire naturelle, appliquée aux arts, à l'agriculture, à l'économie rurale et domestique, à la médecine, etc. | volume=Volume 32 | place=Paris | publisher=Deterville |page=407 | language=French | url=https://biodiversitylibrary.org/page/19504276 }} 3. ^1 {{Cite web|url=http://neotropical.birds.cornell.edu/portal/species/overview?p_p_spp=605356|title=Fawn-breasted Tanager (Pipraeidea melanonota)|website=Cornell Lab of Ornithology - Neotropical Birds|access-date=1 January 2016}} 4. ^{{ cite journal | last=Swainson | first=William | author-link=William John Swainson | year=1827 | title=On several groups and forms in ornithology, not hitherto defined | journal=Zoological Journal| volume=3 | issue=10| pages=158-175 [173] | url=https://biodiversitylibrary.org/page/27485699 }} 5. ^{{cite web | last=Jobling | first=J.A. | year=2018 | title= Key to Scientific Names in Ornithology | editor1-last=del Hoyo | editor1-first=J. | editor2-last=Elliott | editor2-first=A. | editor3-last=Sargatal | editor3-first=J. | editor4-last=Christie | editor4-first=D.A. | editor5-last=de Juana | editor5-first=E. | work=Handbook of the Birds of the World Alive | publisher=Lynx Edicions | url=https://www.hbw.com/dictionary/key-to-scientific-names-in-ornithology?name=PIPRAEIDEA | accessdate=2 April 2018 }} 6. ^{{cite web| editor1-last=Gill | editor1-first=Frank | editor1-link=Frank Gill (ornithologist) | editor2-last=Donsker | editor2-first=David | year=2018 | title=Tanagers and allies | work=World Bird List Version 8.1 | url=http://www.worldbirdnames.org/bow/tanagers/ | publisher=International Ornithologists' Union | accessdate=2 April 2018 }} 7. ^1 2 3 4 5 6 {{Cite book|title=Handbook of the birds of the world|volume=16.
