Trochilidae

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.

Anthracothorax nigricollis (MPR) : occurs from Panama to northeastern Argentina and southern Brazil. It migrates to higher elevations in August and September and long-distance migration in eastern Brazil is also known ( Schuchmann, 1999). There is one record of breeding activity in lowland Atlantic Forest in SP between September and March, and it departs from this region between April and August ( Aleixo & Galetti, 1997).The species has been recorded in Carlos Botelho State Park/SP from October to April ( Antunes et al., 2013), and is considered locally migratory. According to photographic and banding records, it occurs in the Amazon all year round, where it breeds from April to July. This species seems to vanish from RJ, PR and RS during winter (from May to July), and from ES in June and July. Although there are records for SP during winter, its numbers are low. Records of breeding activity in the South and Southeast are restricted to lower elevations (under 600 m) and centered in the peri- od between October and February (SNA, 2016;WikiAves, 2016). This described pattern is confirmed by museum data (MZUSP, MPEG, MNRJ) although the presence of two isolated records in the winter: in MG in June (MZUSP 97891) and in RJ in July (MNRJ 41474).
