Birds of the Arvoredo Marine Biological Reserve, southern Brazil

Abstract

The Arvoredo Marine Biological Reserve (RBMA) is a protected area in southern Brazil created in 1990 to safeguard the marine biodiversity of the Arvoredo Archipelago. There are only few studies about bird assemblage in most of the Brazilian coastal islands, including this protected area. Therefore, this paper presents the first complete list of birds for RBMA based on data from literature and surveys between 1986 and 2012 on islands and surrounding waters. Birds were recorded during captures using mist-nets and opportunistic observations on land in January 2012, as well as in monthly strip-transects and sectors on sea between 2010 and 2012. The present list includes 84 species (15 captured) from primary data and 22 species from other sources, totaling 106 species from 37 families. Bird assemblage in the RBMA is composed by 44 aquatic birds and 62 landbirds, whereas 13 are endemic to the Atlantic Forest and 12 are threatened. As expected due to the diversity of habitats, Arvoredo and Galé Islands supported the richest assemblages in the RBMA. The number of species in the whole RBMA is smaller than bigger islands elsewhere in the Atlantic Forest domain, but similar to same-sized and same-habitat ones. Our results highlight the importance of this reserve as a suitable and isolated habitat to forest species. Deserta Island is an important site for nesting, resting, and foraging seabirds.

Bird diversity and conservation in the southern coast of Santa Catarina state, Brazil

“…Nevertheless, the total richness observed in our study can be considered intermediate in comparison to other coastal areas of southern Brazil: 120 species were recorded in Ibiraquera lagoon microbasin (Piacentini & Campbell-Thompson, 2006), 227 species in Carijós Ecological Station (Vieira et al, 2014) and 228 species in Pirajubaé Extractive Marine Reserve (Vieira, 2016), all of them in Santa Catarina. Other inventories in the coast of Santa Catarina (e.g., Branco et al, 2004;Grose et al, 2013;Grose & Cremer, 2015;Vieira et al, 2015) were restricted to few habitats (i.e., islands and beaches) and are too local for any comparison. For coastal wetland areas in Rio Grande do Sul, bird richness varies from 170 to 283 species (Vizentin-Bugoni et al, 2015).…”

Intraspecific variation of trace elements in the kelp gull (Larus dominicanus): influence of age, sex and location

“…The feeding habits of Larus dominicanus are based mainly on fish and invertebrates, but the species exhibits flexibly habits and can easily adapt to urban environments, feeding on garbage and food debris as well as fishery discards ( Miotto et al., 2016 ). In this sense, improving the knowledge about Larus dominicanus can be important to understand the bioaccumulation and toxicity of metals by birds in coastal areas ( Parrish and Zador, 2003 , Vieira and Serafini, 2016 ).…”
