Population justification: The population size is preliminarily estimated to fall into the band 1,000-2,499 individuals. This equates to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend justification: Despite a lack of direct estimates of the population size or trend, moderately rapid declines are suspected to be continuing, owing to habitat degradation and reduced reproductive success through nest-parasitism by M. bonariensis.
