Sporophila ruficollis (MPR):occurs in northern and eastern Bolivia, western and central Paraguay, northern Argentina, northern and western Uruguay and Brazil (Jaramillo, 2011b). It arrives on the breeding site in late November and remains there until December; a large part of the population overwinters in the Cerrado in MT and in other hotter, more humid regions on the continent (Jaramillo, 2011b; Azpiroz et al., 2012). In Brazil, it breeds only in a restricted area on the western border of RS (FZBRS, 2013). It has been observed in interspecific flocks together with their Amazonian and Central Brazilian congeners (Sick, 1997) and composing mixed flocks – mainly represented by Sporophila bouvreuil – foraging in pastures in the Araguaia River basin in southeastern PA in mid-September 2009, 2010 and 2013 (Cavarzere et al., 2015). For southeastern PA and southern TO, there are also records in July, August and September (Somenzari et al., 2011; Dornas et al., 2013; MZUSP). Photographic records show a sparse presence of this species for AM, RO, MT, MS, GO, ES, SP, PR and RS between August and April (WikiAves, 2016; MZUSP; MPEG), and also an influx of individuals that come from outside Brazil in the winter (FZBRS, 2013). Records for AM in September and November contradict the migratory pattern described in the literature, since the species is expected to be restricted to its breeding area (RS) during this time, which allows us to assume the existence of a resident population for this species. Because of this, further studies are necessary to unveil its movements and properly delimit its breeding grounds.
