Gross and histopathological findings in magellanic penguins (Spheniscus magellanicus Forster, 1781)

摘要

Magellanic Penguins, Spheniscus magellanicus Forter, 1781, are bred mainly along the coasts of Chile and Argentina (Bingham, 2002). After the breeding season (September to March), adults and juveniles leave their colonies and migrate north, accompanying the movement of ocean currents, such as the Falkland current (Sick, 1997). During these movements Magellanic Penguins reach the waters off the Brazilian coast, especially off states in southern Brazil as far north as Rio de Janeiro. Occasionally specimens can be found as far north as the state of Bahia (Roos, 2008). Although they do not breed in Brazil, juveniles are found alive and dead along the Brazilian coast outside the breeding season, during the fall and winter (Boersma, 2008; Garcia-Borboroglu et al., 2010). This has been happening for many years as shown from archeological remains (Gaspar, 1999).
