distribution

breeds in the Arctic, in the coastal tundra region, primarily between 57 ° N and 80 ° N. It overwinters on oceans in the Southern Hemisphere, especially near the coast of South America, southern Africa, southern Australia and New Zealand. It is mostly a transequatorial migrant and few individuals overwinter in the Northern Hemisphere. It departs from the colony in August flying south along the coast. The return journey is quick and happens between April and May (Furness, 1996). On the Brazilian coast, particularly in RJ, it occurs in larger numbers in January, but there are records from March to May and from September to December. One individual banded as a chick in Finland was recovered in RJ in June and another banded in Scotland was recovered in AL in May (Sick, 1997). The species occurs regularly on the coast of SC, and although most records and most individuals are from November to April (Piacentini et al., 2005), there are occasional records throughout the year, which also happens in RS (Belton, 1994; WikiAves, 2016). For all other states (PA, MA, PI, CE, RB, BA, ES, RJ, SP and PR), records are restricted to the period between September and May (WikiAves, 2016; MZUSP).
