Habitat loss and capture for the cagebird trade have likely been the major causes of declines in this species. It was formerly widespread (yet local) in Paraguay, northern Argentina, southern Brazil and Uruguay. It had become rare by the early second half of the 19th century, and there have been only a few reports from the 20th century onwards. The last likely observations of the species were from Mbaracayu, Paraguay, in the late 1990s and 2001.
Following methods developed in a series of papers published in 2017 (Akcakaya et al. 2017, Keith et al. 2017, Thompson et al. 2017), Butchart et al. (2018) calculate the probability that the species is extant based on records and surveys as 0.425, and the probability it is extant based on threats as 0.127, and thus recommend it be classified as Critically Endangered (Possibly Extinct).
