“…The scarlet ibis colony studied is located on Jarivatuba Island (26º2966.45S, 48º7958.14W), Babitonga Bay, with an area of about 136,645 m². It is a recently formed island, with several islets covered in mangrove, which are influenced by tidal variations (16) . The island is located in the city of Joinville, the largest city in Santa Catarina State, where only 31% of sewage is treated (17) .…”

Wild birds are important for public health because of their potential to transmit pathogenic microorganisms to humans. The waterbird scarlet ibis (Eudocimus ruber) forages and breeds near urban areas and if they settle near polluted waters, the viability of adults and their young can be negatively affected. Hence, the aim of this study was to evaluate the cloacal aerobic bacteria profile of nestling scarlet ibis in a mixed colony in Jarivatuba Island, in Joinville, Santa Catarina, Brazil. Cloacal swab samples were collected from clinically normal scarlet ibis nestlings during the breeding season of 2015/2016 (n=16) and 2016/2017 (n=34), and plated onto blood, MacConkey, and Salmonella-Shigella agar plates. Escherichia coli, Proteus vulgaris, Proteus spp., Klebsiella sp., Enterococcus spp. and Staphylococcus spp. were isolated and may be representative of the normal microbiota of E. ruber, although the normal profile is unknown for the species. However, the location of this colony in an area without adequate sewage treatment, which receives domestic effluents, may indicate a modified bacterial profile. Further studies are needed, to better understand the host's natural microbiome, as well as on the bacterial isolates, in order to characterize any association with the contaminated water. These results lay the foundation for successful species conservation projects in the area by providing insights that will help improve the viability of nestlings in each reproductive season.

“…O início das chuvas também estimulou a atividade reprodutiva dos guarás na Ilha do Cajual, no Maranhão (Hass et al 1999). Fink & Cremer (2015) e Grose (2016) também citam que o guará inicia a atividade reprodutiva com o período das chuvas na Baía da Babitonga, Santa Catarina, com adultos se reunindo e disputando território em dezembro. Diante deste cenário, pode-se supor que a não observância de guarás entre outubro e dezembro (meses chuvosos na área monitorada) se dá em função do seu deslocamento para outras áreas provavelmente relacionadas à sítios de reprodução; e que o maior número de avistamentos de indivíduos em janeiro seja reflexo do retorno dos adultos e, posteriormente, dos jovens à área após esse deslocamento.…”

“…guará, Eudocimus ruber (Aves: Threskiornithidae), está intimamente relacionado aos ambientes de manguezal na costa brasileira (Sick 1997). De hábitos gregários, costuma formar colônias reprodutivas e agruparem-se em sítios de repouso em áreas úmidas partilhadas com outras espécies, como colhereiros (Platalea ajaja) e garças (Bubulcus ibis, Ardea alba, Egretta thula e E. caerulea) (Zanin et al 2008, Fink & Cremer 2015, Paludo et al 2018.

The Scarlet Ibis occurred in large numbers at the coast of Paraná until the nineteenth century, but a drastic decrease in its population ended with regional disappearance. The return of the species to São Paulo coast since the 1980s has been projecting its gradual reestablishment towards the southern Brazil. Here we studied the Scarlet Ibis in a mangrove ecosystem in the Paranaguá Estuarine Complex. Eighteen campaigns were conducted from October 2012 to September 2013, in an area between the bays of Laranjeiras and Pinheiros, totaling 1559 counts. Adult specimens accounted for 91.73 %. The largest group was observed in January and comprised 225 individuals, although groups were more consistently large between April and August (which corresponds to the least rainy season). This study suggests that Scarlet Ibis are recolonizing Paraná and that mangrove ecosystem preservation is extremely important to sustain the increase of Scarlet Ibis population.
