“…Este ambiente constitui importantes áreas de descanso e forrageamento para aves das famílias Charadriidae e Scolopacidae. Sazonalmente o Brasil recebe grande contingente de aves migratórias vindas dos Hemisférios Norte e Sul (Morrison & Ross 1989, Sick 1997, Alves 2007, Costa & Sander 2008, Costa et al 2011.…”

“…Esses deslocamentos são mais evidentes com a proximidade do inverno no Hemisfério Norte, quando a redução na oferta de alimento e fatores endógenos indicam o momento da migração nas aves aquáticas (Hayman et al 1986, Azevedo Junior et al 2002, Costa et al 2011.…”

“…Os migrantes que abandonam a América do Norte durante o inverno utilizam várias rotas rumo às áreas de alimentação na América do Sul (Morrison 1984, Morrison & Ross 1989, Myers et al 1990, Sick 1997, Alves 2007, Costa & Sander 2008, Costa et al 2011) sendo que uma das mais utilizada pelas batuíras (Charadriidae) e maçaricos (Scolopacidae) inclui a Ilha Comprida, no litoral Sul de São Paulo (Barbieri & Paes 2008). Na Ilha Comprida, a praia com substrato arenoso é a principal área utilizada pelas aves migratórias (Barbieri & Pinna 2005), bem como local de reprodução de Charadrius collaris e Himantopus paliatus (Barbieri & Delchiaro 2009 (Sick 1997).…”

Abstract:We recorded the frequency of occurrence and monthly fluctuations of Charadriidae and Scolopacidae along a 70km transect of beach between Boqueirão Sul and Boqueirão Norte north of Comprida island, São Paulo State over a 1-year period (Jan -2010 to Dec -2010. A total of 12.153 shorebirds were recorded. The greatest abundance occurred between October and April and the lowest occurred between May and September. The most abundant of the 20 species recorded were Charadrius semipalmatus, Charadrius colaris, Vanellus chilensis and Tringa flavipes. The least abundant were Tryngites subruficolis, Limosa haemastica, Tringa melanoleuca and Actitis macularia. Sixteen species were migrants from the Northern Hemisphere, two were migrants from the Southern Hemisphere, and two were residents. Seven species were recorded regularly, five were recorded sporadically, and eight were recorded occasionally. Four Nearctic species were recorded in June and July most likely indicating the presence of non-breeding immature. The number of species and the number of individuals probably fluctuated due to migration or movements between neighbouring beaches. The Comprida Island beach is important migration stopover and wintering sites for many shorebirds in south São Paulo and should be a focus of conservation efforts, especially given the increasing development pressure that threatens these areas.

“…erefore, this high productivity stimulates the presence of many bird species in this area. ere are 38 south migrant species occurring over the continental shelf waters o Brazil mainly during the austral winter period, most of them belonging to the order Procellariiformes composed of albatrosses and petrels (Costa et al, 2011). Individuals belonging to this order show long lifespan and high reproductive rate (Furness & Monaghan, 1987).…”

In this study, we aimed to analyze the distribution and abundance of subantarctic and Antarctic seabirds along the o shore route between Rio Grande (RS) and Rio de Janeiro (RJ). ree surveys were performed during April in 2011, 2012 and 2013. On board censuses were conducted to evaluate the abundance and distribution of seabirds. e most abundant species was the Atlantic yellow-nosed albatross alassarche chlororhynchos, with 51 individuals and the least species abundant was the Blackbellied Storm Petrel Fregetta tropica, with only two individuals. Latitude 29° S showed the largest abundance of seabirds (n=41), whereas the smallest abundance was observed at latitude 24º S (n=2). e highest richness was observed at latitudes 26° S and 30º S (n=5 in each degree).We conclude that most birds that use the Brazilian coast as a foraging area are actually south migrant species and that further studies are necessary to assess factors which may explain the distribution of these birds.

“…However, South America also harbours important breeding sites for seabirds (e.g. Yorio et al 1999;Simeone et al 2003) and oceanic and/or coastal areas offer wintering sites for Antarctic and Sub-Antarctic seabirds (reviewed by Costa et al 2011) as well as Northern Hemisphere seabirds (e.g. Spear & Ainley 2008).…”

Impacts of climate variation and potential effects of climate change on South American seabirds – a review

The coastal and oceanic waters around the South American coasts provide rich foraging grounds for breeding and wintering seabirds, but there is growing concern that climate change will provide additional pressures to the seabirds around South America. As in many other coastal ecosystems, seabirds around South America are already faced with threats to their breeding habitats such as human disturbance and introduced predators, and threats at sea such as persistent pollutants and pesticides and direct mortality risks due to fisheries and oil spills. The sensitivity of South American marine ecosystems to ocean climate anomalies is well known from the dramatic population collapses caused by El Niñ o Southern Oscillation (ENSO) events. However, longer-term climate change effects have been explored less often and few long-term data sets exist for South American seabirds. Seven Large Marine Ecosystems (LME) border South America. While all LMEs experienced warming during the last 50 years, their climate dynamics have differed in recent decades. Climate models suggest that potential climate change effects may be important, especially due to changes in ENSO intensity and frequency and associated changes in the ocean climate of Atlantic and Pacific marine ecosystems. In this review, we found that the best studied seabird communities are those of the Patagonian Shelf and the Humboldt Current, but overall, our knowledge on climate effects on South American seabirds is scarce.
