Sporophila caerulescens (MPR):occurs in Bolivia, Paraguay, Argentina, Uruguay and almost all of Brazil. Its movement pattern is not fully understood. Some populations are resident, while the ones further south of its distribution migrate north during winter and are recorded only seasonally in some areas such as eastern Peru and Central Brazil (Jaramillo, 2011a). In Argentina, large numbers of males are captured alone in November and December. It has been suggested that they leave first for winter migration north in February, since only females and their young that had yet to molt into full adult plumage were observed in the end of summer and beginning of fall. Populations from northeastern and northwestern Argentina are also peculiar: they migrate in different directions and for different distances (Ortiz & Capllonch, 2007). In Brazil, the species flies over the Pantanal when moving from the south to the north of the country especially in April, as well as when returning south in September (Sick, 1997). However, photographic records for the Pantanal show its presence in MT between May and December and in MS from April to November and in February (WikiAves, 2016). In RS, most individuals seem to disappear during winter (Belton, 1985). There is evidence of breeding activity between September and May and it is restricted to GO and other states from the Southeast and South (Belton, 1985; Maurício et al., 2013; WikiAves, 2016), which suggests that the species is partially migratory. Further studies are still necessary to fully comprehend its movements.
