Population justification: The species's population was recently estimated at c.100,000 individuals, based on an estimated 10,000 km2 of habitat and a density of 10 individuals/km2 (M. F. de Vasconcelos in litt. 2007); however, this may be an overestimate (L. E. Lopes in litt. 2009), thus the population is placed in the band 50,000-99,999 individuals pending further study.
Trend justification: Although it is suspected to be declining locally, owing to habitat degradation at the type locality and some localised brood-parasitism by Molothrus bonariensis, the species is suspected to be stable across the majority of its range.
