Turdidae

Turdus amaurochalinus (MPR) : occurs in Peru, Bolivia, Paraguay, central and northern Argentina, Chile, Uruguay and almost all of Brazil ( Collar & Juana, 2015), but with few records for the Amazon. During austral winter, many individuals fly northwards, and flocks fly over RJ in late April and early May, reaching MA and eastern PA ( Sick, 1997) mainly between June and October.The large number of individuals of this species in the southeast coast of Brazil between June and July may be because of immigrants coming from regions further south ( Collar & Juana, 2015). During migration, a large number of individuals from southern population cross the marshes east of Tucumán and west of Santiago del Estero in Argentina to Bolivia and Peru between May and June. Another part of the migration occurs east going up along the Atlantic coast to northeastern Brazil. The return migration in spring starts in October in northern Argentina. There is a population that is supposed to be resident in the convergence zone of the Paraná and Uruguay Rivers, in a large region of deltas and marshes in the provinces of Entre Ríos and Buenos Aires ( Capllonch et al., 2008). The species breed in multiple localities – CE, MS, GO, MG, RJ, SP, PR, RS – in Brazil (WikiAves, 2016; Maurício et al., 2013). Photographic and museum records document its presence mainly from September to January in southeastern and southern regions, while in central-western and northeastern Brazil they seem to be irregularly spread throughout the year (WikiAves, 2016; MZUSP; MNRJ; MPEG). Although these records do not suggest a migratory pattern probably due to the coexistence of resident and migratory populations, banding and recovery data confirms is movement between the south of the country and RJ in January and June respectively (SNA, 2016).

Turdus subalaris (MPR) : occurs in Paraguay, Argentina and central-western, southeastern and southern regions of Brazil ( Collar, 2016). The cis-andean population is migratory, breeds in southern Brazil, Argentina and the border with Paraguay, and seems to overwinter in the eastern part of the Cerrado/Amazon transition, flying over Brasília/DF between September and October ( Antas & Valle, 1987; Ferreira & Bagno, 2000; WikiAves, 2016). In addition, there are records for PA ( Somenzari et al., 2011), TO ( Pinheiro et al., 2008),RJ ( Pacheco et al., 2010),MT, GO, BA, MG, SP, PR, SC and RS ( Grantsau, 2010). In SC and RS, it has been recorded in large numbers from September to April and there is also evidence of breeding activity ( Belton, 1985; Maurício et al., 2013). Museum records are centered in the period of April-September in the states of PA,TO, MT, GO, BA, SP and SC (MZUSP; MPEG).
