Diversity of birds in the Mata do Junco State Wildlife Refuge, a remnant of the Atlantic Forest of Northeastern Brazil

Abstract

Abstract:This study presents an inventory of the bird fauna of the Mata do Junco State Wildlife Refuge in Capela, in the northeastern Brazilian state of Sergipe. Monthly samples were collected between January 2011 and May 2012. Each 3-day sample was based on mistnetting (100 m) in two areas and the compilation of MacKinnon lists of 10 species. During the 17 months of the study period, the occurrence of 129 bird species belonging to 41 families was confirmed for the study area. In the mist-nets, a total of 469 individuals representing 58 species were captured in 3400 net-hours of sampling effort. A total of 100 MacKinnon lists were compiled, resulting in an inventory of 119 bird species. Eight of the species are endemic to Brazil, of which, five are restricted to the Brazilian Atlantic Forest. Three of the species are included in the IUCN Red List, at different levels of concern. Overall, the results of the study indicate that the Mata do Junco represents an important area for the protection of the region's avian fauna and the habitats they rely on.

New range limit of the Anopetia gounellei (Aves: Trochilidae): state of art and a review on the updated area

“…Studies concerning seasonality of A. gounellei reported the species on caatinga and humid vegetation in both dry and rainy seasons, as well as resident and occasional (Olmos, 1993;Santos, 2004;Leal et al, 2006;Santos et al, 2012;Silva et al, 2012;Silveira & Santos, 2012;Ruiz-Esparza et al, 2015). We found only one seasonality record for cerrado-like vegetation which reported A. gounellei as occasional on an area close to caatinga, and during a severe drought (Machado, 2014).…”

“…The climate classification varied among authors, field areas and classification systems. For the Köppen system we were able to find presence records on dry semiarid (Bsh), tropical with dry winter (Aw), tropical with dry summer (As) and humid tropical with dry winter and temperate summer (Cwb) (Sick et al, 1987;Dornelas et al, 2012;Machado, 2014;Ruiz-Esparza et al, 2015) areas, and for the IBGE system the climate varied among semiarid, subtropical with moderate humidity and tropical with rainy summer (Neves et al, 2011;Nunes & Machado, 2012;Las-Casas et al, 2012a, b;Ruiz-Esparza et al, 2012;Silva et al, 2012;Silveira & Machado, 2012).…”

“…At the highest altitudes many studies reported more humid vegetation such as seasonal semi-deciduous forest and ombrophilous forest (Parrini et al, 1999;Pacheco, 2003;Farias et al, 2005;Albano & Girão, 2008;Demetrio, 2008;Santos et al, 2012). Humid vegetation also appeared in lowlands (Silva, 2009;Silva et al, 2012;Ruiz-Esparza et al, 2015). However, the majority of vegetation recorded belongs to the caatinga type, ranging from shrubby caatinga to dense arboreal caatinga Olmos et al, 2005;Leal et al, 2006;Vasconcelos et al, 2006;Farias, 2007;Araujo et al, 2012;Olmos & Albano, 2012); cerrado and rocky fields were also reported but in a small number (Dornelas et al, 2012;Machado, 2014;Pereira et al, 2014).…”

Avifauna no Refúgio de Vida Silvestre Mata do Buraquinho, João Pessoa, Paraíba, Brasil, com notas naturalísticas sobre as espécies ameaçadas

“…Na comunidade de aves, 28 espécies são consideradas indicadoras de alterações de habitat, tal como em florestas secundárias (Ruiz-Esparza et al, 2015) . Destas, seis táxons estão ameaçadas de extinção em diferentes categorias de ameaças (Brasil, 2018b; IUCN, 2020) (Tabela 3; Figura 6).…”
