Pygochelidon melanoleuca (MGT): occurs in extreme eastern Colombia, southern and eastern Venezuela, Guianas, Amazon and southern Brazil, and there are occasional records for southeastern BA, upper Paraná River, southern GO and for the border between Brazil and Argentina in Iguazu Falls (Turner, 2016a). It associates with rivers that have falls and rapids (Sick, 1997). In RO, forms large flocks, breeds from June to October, uses emerged stony grounds on river channels and vanishes when rainfall starts in mid-November (M. Somenzari, pers. obs.). Records for the Amazonian region in RR, AP, AM, PA, RO, MT and TO are centered in the period between April and November, but there are also records for GO and for MG in almost all months of the year (WikiAves, 2016).
