“…The Andean populations from central Peru northwards seem to be year‐round residents (Henry, 2012; Ridgely & Greenfield, 2001). On the other hand, populations of southern Peru and Bolivia seem to carry out eminently altitudinal migrations, descending eastwards to the lowlands during the winter (Parker, 1982; Schulenberg, 2010), while the Andean, Central Sierras and Pampas populations of Argentina migrate latitudinally to the north during fall migration (with some altitudinal [mostly descent] and some longitudinal components), overwintering in the Paraguayan and Brazilian Pantanal, Bolivian Chiquitanía, southern coast of Brazil and humid Chaco of Paraguay and Argentina (Bornschein et al., 2017; Chesser, 1997; de Vasconcelos et al., 2008; Herzog et al., 2016).…”
