  • <p><i>Tiaris obscurus</i> (VAG):</p><p>occurs from the region of the Andes in western Venezuela south as far as northwestern Argentina (Rising, 2011). It is resident in a large part of its distribution, but it may move altitudinally from the Andes to lowlands after breeding (Rising, 2011). Migratory movements are still little known, but records in Brazil suggest that this species overwinters in the regions of Chiquitano and Pantanal (Whittaker & Carlos, 2004; Vasconcelos <i>et al.,</i> 2008 a). There are no photographic records of this species in the national territory (WikiAves, 2016).</p>
