Further comments on the avifauna of the middle Sao Francisco Valley, Minas Gerais, Brazil

摘要

In earlier contributions (Kirwan et al. 2001, Raposo et al. 2002, Whitney et al. 2003) GMK, JMB and others drew attention to the highly threatened avifauna of the middle reaches of the no Sao Francisco in eastern Brazil, and the river's importance ininfluencing biogeographical processes of avian speciation and endemism. We also presented notes on behavioural aspects of a number of poorly known species, and provided new southernmost records for several north-east Brazilian caatinga specialists. Details of our principal study sites were included in the earlier paper. Since then we have made further visits to the area, resulting in additional data substantially augmenting our previous field work. Here, our intention is only to supply details of thoserecords that update our knowledge of the Minas Gerais avifauna, along the middle reaches of the Sao Francisco Valley. Systematic order and scientific nomenclature follow Sick (1997), with all departures from this explained in Kirwan et al. (2001).
