Pterodroma arminjoniana (MPR): adults seem to be sedentary in great part of its distribution while immature individuals are more dispersive and can move through tropical and subtropical Atlantic waters. It breeds in Trindade and Martin Vaz (Carboneras, 1992c), but its breeding is currently restricted to Trindade Island and other near islets (Neves et al., 2006). On Trindade, active nests and pairs doing flight displays can be seen all year round (Neves et al., 2006), but records of immature individuals are more common on the North Atlantic Ocean than in the South Atlantic (Abreu et al., 2010). There are, however, records of adults for the coast of Rio Grande do Norte (RN) in January 2015 (WikiAves, 2016) and of immature individuals for Argentina in July (Savigny et al., 2005) and for Uruguay in April (Abreu et al., 2010).
