Florisuga fusca (MPR): occurs in southeastern Paraguay, northeastern Argentina, northern Uruguay and part of Brazil (Schuchmann, 1999). It breeds on mountains in southeastern Brazil and migrates altitudinally, moving to lower grounds during winter. It is a regular winter visitor in the province of Misiones in Argentina and rare in eastern Paraguay (Areta & Bodrati, 2010). In Brazil, there are records in all months of the year in the Southeast, the South, and in BA. In GO and MS, records are centered in the period between April and October. Breeding activity (November to March) has an altitudinal tendency, and most records come from elevations higher than 600 m (WikiAves, 2016). Further studies are necessary to better understand its migratory patterns.
