On the one hand, documented records in northern Bahia ( e.g., WA 4346261; P.E. Matos ) and records in Pernambuco ( Sousa et al., 2012 ) suggest that this species’ occurrence in Alagoas is not unlikely and, therefore, that Teixeira et al. ’s (1989) records may be valid. On the other hand, it is odd that many flocks were observed, and the species seemed to be common in Alagoas (Teixeira et al., 1989), but it has never been recorded again in the state despite extensive ornithological surveying and birdwatching in Quebrangulo (Studer, 2015; WikiAves, 2021), and thus there remains a possibility that Teixeira et al. ’s (1989) records might be misidentifications of Diopsittaca nobilis , which is known from these sites.We tentatively treat the abovementioned undocumented records as valid considering that the species’ occurrence in Alagoas is not unlikely .
