Rallidae

Porphyrio flavirostris (ND) : occurs from eastern Colombia through southern central Venezuela to the Guianas, south as far as eastern Ecuador, northern and southeastern Peru, northern Bolivia, and central Paraguay to extreme northern Argentina, and there are also sparse records in the entire Brazil ( Taylor, 1996). Its occurrence is highly seasonal in parts of its distribution and it seems to coincide with the flood season: in southwestern Amazon and Paraguay, it occurs mainly between October and January; in eastern Amazon, between February and August; in western Amazon, records peak in January; and in the Upper Amazon, it is present only between January and July. It is considered vagrant in southern Brazil (Remsen Jr. & Parker III, 1990; Taylor, 1996; Dias et al., 2010b). Photographic records do not corroborate the pattern described in the literature.The occurrence of this species in the South region is restricted to sporadic records for all three states ( Dias et al., 2010b; Meyer, 2015). More data is necessary to classify this species as migratory.Individuals collected in Fazenda Fartura in Santana do Araguaia/PA had developed gonads, which indicates that the species breeds in Brazil (L.F. Silveira, pers. obs.). Museum collection data are restricted to MT in May and in PA in March, April, August, November and December (MPEG).
