Elaenia spectabilis (MPR):breeds from the eastern Andes in Bolivia to southwestern and eastern Brazil, northern Argentina and Uruguay; it overwinters in northeastern Brazil and in the Amazon (Hosner, 2004a). Museum and sound records show its sparse presence throughout the year in almost the entire national territory. Records for Amazonian states are restricted in the period between April and November and centered between May and August (WikiAves, 2016; MZUSP; MNRJ; MPEG).The records from the South region (PR, SC and RS) are restricted to September and March (WikiAves, 2016; MZUSP; MPEG), which suggests a migratory pattern. However, there is only evidence of breeding activity for the Northeast, Southeast and South regions between September and April (WikiAves, 2016) indicating why this species was classified as partially migratory.
