“…The present study focused on Coroa do Avião Island, which is located on the southern bar of the Santa Cruz Channel (7°49’00” S, 34°50’15” W), north of Maria Farinha Beach and south of Itamaracá Island on the northern coast of the Brazilian state of Pernambuco [ 19 ] (Figure 1 ). This island is part of the region’s coastal zone and one of the most important overwintering sites for migratory shorebirds in northeast Brazil [ 18 – 20 , 45 , 55 ]. Fig.…”

“…South America is visited by approximately 2.9 million migratory shorebirds each year [ 14 , 15 , 17 ], and the northeastern coast of the continent includes a number of areas that are considered key sites for migratory shorebirds that follow the Atlantic migratory route [ 16 , 18 – 21 ]. These overwintering sites are used by the birds to recover from their long migratory flights and to forage for food to accumulate body fat for the return journey to the Northern Hemisphere [ 22 ].…”
BackgroundThis paper discusses the results of ethno-ornithological research conducted on the local ecological knowledge (LEK) of artisanal fishers in northeast Brazil between August 2013 and October 2014.MethodsThe present study analyzed the LEK of 240 artisanal fishermen in relation to Nearctic shorebirds and the factors that may be affecting their populations. We examined whether differences occurred according to the gender and age of the local population. The research instruments included semi-structured and check-list interviews.ResultsWe found that greater knowledge of migratory birds and the areas where they occur was retained by the local men compared with the local women. Half of the male respondents stated that the birds are always in the same locations, and most of the respondents believed that changes in certain populations were caused by factors related to habitat disturbance, particularly to increases in housing construction and visitors to the island. The main practices affecting the presence of migratory birds mentioned by the locals were boat traffic and noise from bars and vessels. According to the artisanal fishermen, the population of migratory birds that use the area for foraging and resting has been reduced over time.ConclusionsChanges in the local landscape related to urbanization and tourism are most likely the primary causes underlying the reduced migratory shorebird populations as reported by local inhabitants. Thus, managing and monitoring urbanization and tourism are fundamental to increasing the success of the migration process and improving the conservation of migratory shorebird species.

“…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.…”
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.
“…In March, individuals with intermediate or breeding plumage begin to appear, increasing in frequency in April and May (the months in which this species begins its migration towards the northern hemisphere) (AZEVEDO-JÚNIOR et al 2001). During May and June, large flocks of these birds concentrate on the eastern coast of North America (CLARK & NILES 1993).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
