Taxonomy

Taxonomic note
Suiriri suiriri (del Hoyo and Collar 2016) and the previously named S. affinis remain lumped following SACC (2005), however the type of S. s. affinis has been shown to refer to the form subsequently described as Chapada Flycatcher (previously S. islerorum), hence the latter receives the name S. affinis and the subspecies formerly described as S. s. affinis takes the new name S. s. burmeisteri Kirwan 2014.

Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: The population is declining owing to widespread habitat conversion to pine and eucalyptus plantations and soy-bean and rice crops as well as habitat clearance for livestock farming (del Hoyo et al. 2004).
