This species is listed as Vulnerable because its population is small and declining rapidly owing to ongoing deforestation. It has been found to be more resilient to forest fragmentation than first thought, and it may be under-recorded rather than genuinely scarce, especially in the southern part of its range.

|Range Description:||Touit surdus occurs in north-east Brazil (Ceará, Paraíba, Pernambuco, Alagoas and Sergipe), and in the south-east from Bahia south to Rio de Janeiro (L. F. Silveira in litt. 2012). Recent surveys have found it to be one of the commonest parrot in the Atlantic Forest of Alagoas (which has been reduced to <2% of its former extent), being present in 5 out of 15 sites surveyed (L. F. Silveira et al. in litt.) and also in Murici Ecological Station (J. M. Barnett in litt. 2002). It was also recently found nesting in arboreal termitaria in forest fragments in Pernambuco (Telino et al. 2000). The species was found in 16 out of 31 surveyed areas in southern Bahia, including the private reserves Ecoparque de Una and Estação Veracruz (formerly CVRD Porto Seguro reserve), Una Biological Reserve, and Descobrimento, Pau Brasil and Monte Pascoal National Parks (Cordeiro 2002).|

|Population:||The species is generally rare; its population is placed in the band 2,500-9,999 mature individuals, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: A rapid and on-going population decline is suspected on the basis of continuing habitat destruction and fragmentation.
