Porphyrio martinicus (MPR):occurs from southeastern USA to Peru, Paraguay, Uruguay, northern Argentina and all of Brazil (Taylor, 1996; Grantsau, 2010). Although the literature indicates that this species moves seasonally in northeastern Brazil (Sick, 1983), photographic records (WikiAves, 2016) and banding data (SNA, 2016) do not corroborate this pattern. There are scarce records of breeding activity in the entire Northeast region from January to October, and also in CE, Pernambuco (PE) and BA throughout the year (WikiAves, 2016). Populations from the extreme south of the distribution (Argentina,Uruguay and southern Brazil)fly north during austral winter (Taylor, 1996), when they disappear completely (Sick, 1997) from the RS,where records are restricted to the period between September and May (Belton, 1984; MZUSP 637 [RS, 1897, October]), when they also breed (Maurício et al., 2013). As the species is recorded virtually all year round in SC (WikiAves, 2016), migration seems to be restricted to RS.
