Tyrannidae

[ Pseudocolopteryx dinelliana ] (VAG): occurs in Bolivia, Argentina and Paraguay. It migrates to extreme southern Bolivia and western Paraguay during austral winter ( Bostwick, 2004b). In Brazil, there is only one undocumented record for the Binational Maracaju Sanctuary/MS close to the border with Paraguay, but this document has been lost ( Pérez-Villamayor et al., 2014).

Tyrannus dominicensis (VAG) : breeds in southeastern USA, Bahamas, Greater Antilles, Trinidad and Tobago, CuraÇao, Bonaire, locally in central Venezuela and possibly in northern Colombia. It overwinters from southern Panama to central Colombia and southern and eastern Venezuela. Most populations migrate during boreal winter in November and the species occurs irregularly in extreme northern Brazil ( Mobley, 2004i). It also occurs in the Guianas as a regular visitor (Paynter Jr., 1995). There are few records of this species in Brazil: it was observed occasionally in Amapá (AP) and in RR, where it was also photographed (WikiAves, 2016), and in AM ( Nassar & Melo, 2015).

Alectrurus risora (VAG) : occurs in northern Argentina, eastern Paraguay and Uruguay and there are localized records for Brazil (mostly historic) in southern MT, MS, SP and RS ( Grantsau, 2010). There is also a historic accidental record for RJ ( Pacheco & Gonzaga, 1994). In the past, a population from northeastern Argentina bred in the province of Buenos Aires and wintered in Brazil. Current populations are resident throughout the year and do not migrate to Brazil anymore ( Di Giácomo & Di Giácomo, 2004).There is only one photographic record for the Brazilian territory for Bonito/MS in August (WikiAves, 2016).

Knipolegus striaticeps (VAG) : occurs in eastern and southern Bolivia, western Paraguay, northwestern Argentina and it reaches Brazil at the end of the austral winter, between August and September ( Sick, 1997) near Corumbá/MS ( Tubelis & Tomas, 2003). The movement pattern of this species is still unknown, but migratory movements have been observed in the south part of its distribution ( Farnsworth & Langham, 2004c). In Brazil, there are no photographic records available (WikiAves, 2016) although there are two specimen from MS collected in May 1944 (MZUSP).

Knipolegus hudsoni (VAG) : breeds in central Argentina, flies north during winter in August and September, and reaches Paraguay, Bolivia and eventually Brazil in MT and MS ( Sick, 1997). The Serra do Roncador seems to be the northern limit of its migration ( Farnsworth & Langham, 2004d). There are photographic records for MS in April, July and August (WikiAves, 2016).

[ Knipolegus aterrimus ] (VAG): occurs from southern Bolivia to western Argentina and migrates north in March- April to winter in Paraguay and northeastern Argentina ( Farnsworth & Langham, 2004e). In Brazil, there are few records and all of them are near the western and southwestern border of the country in MS and RS ( Bornschein et al., 2003; Farnsworth & Langham, 2004e; WikiAves, 2016).

Muscisaxicola maclovianus (VAG) : is a migratory species that breeds in southern Chile and Argentina and overwinters in northern Peru, northeastern Argentina and Uruguay ( Farnsworth & Langham, 2004f). In Brazil, there is one record for the Lagoa do Peixe National Park/RS in May ( Schwertner et al., 2011) that is linked to seven photographs, and two other photographic records for Rio Grande/RS in June (WikiAves, 2016).

Xolmis rubetra (VAG) : occurs in Argentina, breeds in central Argentina and migrates north during winter ( Farnsworth & Langham, 2004g). In Brazil, there is only one record for extreme western RS in August ( Bellagamba-Oliveira et al., 2013), and two photos available at WikiAves (2016).

Agriornis micropterus (VAG) : occurs from southern Bolivia to Santa Cruz Province in Argentina and breeds in the steppes and prairies from southern Peru to the province of Santa Cruz. Populations from the south of its distribution are represented by the nominate subspecies and are migratory. It departs from its breeding areas at the end of the summer in February and migrates north to spend the austral fall and winter in southern Bolivia, Paraguay, Uruguay and part of northern Argentina. It is rare in Paraguay and Uruguay ( Farnsworth et al., 2016). In Brazil, the first documented record was obtained for extreme western RS in September 2012. Although this species may be a regular migrant of low density in Brazil ( Bellagamba et al., 2014), here it is considered vagrant due to a lack of data that corroborates this hypothesis and to the fact that there is only one record in Brazil.

Agriornis murinus (VAG) : breeds from October to March in plains with scattered shrubs in northwestern and southern central Argentina, and migrates to the north of the country, to western Paraguay and southern Bolivia during austral fall and winter, along a north-south axis. It is considered vagrant in extreme southern Brazil ( Farnsworth & Langham, 2004h; Dias et al., 2010b) and there are two photographic records for Rio Grande/RS, one in April and another in July (WikiAves, 2016).

Neoxolmis rufiventris (VAG) : breeds from southeastern Argentina (and extreme southern Chile) south to Tierra del Fuego and migrates north during austral winter to central Argentina and Uruguay ( Farnsworth & Langham, 2004i). There is only one relatively old record for the southwest from Rio Grande in fall 1973, suggesting it is a vagrant species (FZBRS, 2013). In addition, there are photographic records for western RS in June and for the south in April (WikiAves, 2016).
