Nyctanassa violacea(MPR): occurs from the coast of the USAto northern Peruand Brazilin all coastal states from AP to RS ( Sick,1997;WikiAves,2016).Movements from the subspecies N. v. cayennesis,which occurs in Brazil, are little known ( Martínez-Vilalta & Motis, 1992). In the estuary from Lagoa dos Patos/RS, where it breeds, its occurrence is seasonal between August and April ( Gianuca,2007) and a large part of the population is absent from this state between April and August,when its main prey (the crab Neohelice granulata) remains in its burrows ( Martínez-Vilalta & Motis, 1992).There are other records for RS in September, October, November, December and February ( Belton, 1984; WikiAves, 2016), which confirm the migratory pattern in the state even though it is present in all other states throughout the year (WikiAves, 2016).
