“…Larus dominicanus, que teve frequência constante (C = 78%), não foi observado entre dezembro e fevereiro na área do estudo, gerando uma flutuação na abundância, que pode ter sido desencadeada pelos intensos movimentos dessas aves entre vários locais em busca de alimento e descanso, como já verificado em outros estudos (BARBIERI, 2008). Áreas úmidas próximas, como o estuário e lagoas, devem ser monitoradas durante os meses em que a orla é mais antropizada para verificar a possível variação espacial de L. dominicanus, assim como das demais espécies, durante o verão.…”

A avifauna litorânea é um importante elemento na dinâmica dos ecossistemas onde vive, sendo a planície costeira considerada uma área de altíssima prioridade para a conservação da biodiversidade regional. Devido à carência de informações sobre as aves que frequentam o litoral norte do Rio Grande do Sul, principalmente em trechos de intensa ocupação antrópica, e a importância desse grupo como um constituinte da biodiversidade, este artigo objetiva, com vistas à conservação, fornecer dados sobre a avifauna costeira. O estudo apresenta um levantamento das aves marinhas e costeiras, em um trecho entre os municípios de Tramandaí e Palmares do Sul, no litoral norte do estado, estabelecendo a variação sazonal e estimando a abundância de cada espécie ao longo de um ano. O estudo foi realizado em uma extensão de 50 km de beira de praia, percorrida mensalmente com um automóvel, e as aves observadas nesse trajeto foram contabilizadas com auxílio de binóculo. As amostragens ocorreram durante um período de 14 meses. Foram registradas 21.888 aves, de 44 espécies, pertencentes a 20 famílias, que representam 10 ordens. As famílias mais abundantes foram Scolopacidae, Charadriidae, Laridae e Haematopodidae, representantes da ordem Charadriiformes. Palavras-chave: Aves marinhas; Sul do Brasil; Zona costeira AbstractDiversity and abundance of marine birds in a stretch of the north coast of Rio Grande do Sul, Brazil. The coastal avifauna is an important element in the dynamics of the ecosystems where it lives, and the coastal plain is regarded as a very high priority area for preserving the regional biodiversity. Due to the lack of information on the birds which go to the north coast of Rio Grande do Sul, especially in stretches with an intense anthropic occupation, and the importance of this group as a biodiversity constituent, this paper aims, with a conservational purpose, to provide data on the coastal avifauna. The study presents a survey of marine and coastal birds, in a stretch between the towns of Tramandai and Palmares do Sul, in the state's northern coast, establishing the seasonal variation and estimating the abundance of each species throughout one year. The study took place over 50 km of seashore, monthly went through by car, and the birds observed in this route were counted with the aid of binoculars. The samplings took place within the period of 14 months. One recorded 21,888 birds, of 44 species, belonging to 20 families, which represent 10 orders. The most abundant families were Scolopacidae, Charadriidae, Laridae, and Haematopodidae, representing the Charadriiformes order.

“…The second most commonly addressed topic in the region was population studies and bird community structures. Studies of this nature are frequent due to the presence of colonies on the coastal islands of the Santos Basin, particularly of S. leucogaster (Alves et al, 2004;Branco et al, 2010), F. magnificens (Nuss et al, 2016), L. dominicanus (Branco and Ebert, 2002;Barbieri, 2008;Yorio et al, 2016), and, to a lesser extent, Sternidae (Efe et al, 2007;Yorio and Efe, 2008). Much of the knowledge of seabirds in the Santos Basin is with respect to coastal areas and therefore focused on these species (e.g.…”

Ocean and Coastal ResearchThe Santos Basin in eastern Brazil is adjacent to the largest human populations in the southwestern Atlantic Ocean, with several potential threats to marine vertebrates. In this study, we provided a systematic bibliographic review and integrated unpublished primary datasets to provide an overview on species, research topics and gaps, and threats to seabirds in the Santos Basin. Bibliographical sources were used for species recorded within the limits of the basin, while species census data were obtained through research and monitoring projects. We analyzed 156 studies from 1914 to 2021. An increase in the number of publications was observed from the 2000s onward (> 80%), with the state of Santa Catarina showing the highest number of publications (56%) on seabirds. Notes and Records (27%), Population and Community Structure (22%), and Fishing (11%) were the main subjects studied. Among the 76 seabird species reported in the Santos Basin (~2/3 of the species reported in Brazil), Procellariiformes was the most prevalent order (51%), including 14 species listed as threatened, either globally or nationally. Resident (28%) and long-distance migratory species, such as visitors from the Southern (39%) and Northern (17%) Hemispheres and Europe (12%), were widely recorded in the region, as well as vagrant species. The inclusion of different data sources allowed broadening the geographic cover used by species to consider both coastal (predominating in previous studies) and offshore areas. The association of seabird distribution with oceanographic and meteorological features should be addressed in future studies, as should studies on the impact of fishing and pollution on a range of common species.

“…Although the Ilha Comprida beach covers roughly 70 km and is considered an environmental protection area subject to management, there are few studies on species composition, habitat use, or seasonal population changes. This region is becoming a prime tourist destination, so large numbers of people now compete for space with migratory birds during December, January and February (Barbieri 2008). It also supports an intense fishing in dustry, both artisanal and industrial, which affects seabird populations by providing discarded food.…”
