It is closely related to, and was long considered to be the same species as, the Austral negrito of southern South America. The species is monotypic, having no subspecies.[2] DescriptionThe Andean negrito is around {{convert|12.5|cm|in|abbr=on}} long, with males being slightly larger. It is sexually dimorphic in its plumage; males having black plumage with a rufous back and silvery-white flight feathers (that area only noticeable in flight). The female has a rufous back as well but the undersides and head are sooty and the upperparts are blackish brown. The throat is whitish and the breast tinged with dull rufous. The species has exceptionally long hindclaws, like those of a pipit.[2] Distribution and habitatThe Andean negrito ranges through the mountainous regions of central Peru south into western Bolivia, down into north eastern Chile and northern Argentina. It is most commonly found between {{convert|3000|–|4000|m|ft|abbr=on}} above sea level, but may go higher in Peru or drop down to {{convert|1000|m|ft|abbr=on}} in Chile. It lives around lakes, streams and bogs and in seasonally flooded plains, in areas with low ground cover. The species is non-migratory.[2] BehaviourThe Andean negrito is a terrestrial insect hunter that is found in pairs or small family groups. Often perches on elevated tussocks or rocks to watch for prey. Prey is either sallied after on the wing from on or close to the ground, or chased after on foot.[2] Little is known about its breeding behaviour. In Chile it breeds between October and January. Males perform a fluttering display flight that goes {{convert|10|–|15|m|ft|abbr=on}} in the air. Nests are simple cups hidden inside tussock grass, into which 3-4 eggs are laid.[2] References1. ^{{IUCN|id=22700213 |title=Lessonia oreas |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} {{Taxonbar|from=Q1272307}}{{DEFAULTSORT:negrito, Andean}}2. ^1 2 3 4 {{cite web | last1=Farnsworth | first1=A |last2=Lebbin | first2=D |editor1-last=del Hoyo |editor1-first=Josep |editor2-last=Elliott |editor2-first=Andrew |editor3-last=Sargatal |editor3-first=Jordi |editor4-last=Christie |editor4-first=David A |editor5-last=de Juana |editor5-first=Eduardo |year=2018 |title= Andean Negrito (Lessonia oreas) |work=Handbook of the Birds of the World Alive |url=https://www.hbw.com/species/andean-negrito-lessonia-oreas |publisher=Lynx Edicions |location=Barcelona |accessdate=31 December 2018 |subscription=true}} 5 : Lessonia|Birds of the Andes|Birds of the Puna grassland|Birds described in 1869|Taxonomy articles created by Polbot |
