Vireonidae

Vireo chivi (MPR) : breeds between late September and early April in central western and southern Peru, Brazil – in BA, GO, MT, RJ, SP, PR, SC and RS (WikiAves, 2016) –, west-central Paraguay and northern Argentina as far as Buenos Aires, between 15°S and 36°S ( Capllonch & Wagner, 2009; Brewer & Orenstein, 2010). In SP, records are restricted to the period between September and March ( Aleixo & Galetti, 1997; Machado, 1997; Willis, 2004; Antunes et al., 2013; MZUSP), as well as in PR ( Vallejos et al., 2011; MZUSP), the Pantanal ( Nunes & Tomas, 2008), and MS ( Nunes et al., 2011). In PE, records are centered in the period between October and February (W. Telino-Júnior, pers. obs.), while in SE it has been recorded only in December ( Ruiz-Esparza et al., 2011). For RS, there are records between September and May ( Belton, 1985) and for RJ all year round, but it is usually silent between April and August as it follows mixed-species flocks (J.F. Pacheco, pers. obs.). After breeding, it moves to the Amazon and southern Venezuela, where it remains during austral winter ( Capllonch & Wagner, 2009; Brewer & Orenstein, 2010). Its wintering areas are little known, but there are reports for Jaraguá/GO and Chapada dos Guimarães/MT ( Capllonch & Wagner, 2009).
