Brown-backed Parrotlet is endemic to the states of Bahia, Espírito Santo, Rio de Janeiro, São Paulo and Paraná in south-east Brazil. The species is listed as Endangered under C2a(i). The population is estimated at 250-999 mature individuals. A moderate and ongoing population decline is suspected owing to rates of habitat destruction and degradation.
In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Vulnerable under C2a(i). It is estimated that there are <10,000 mature individuals with <1,000 mature individuals in each subpopulation. The population is in continuing decline owing to habitat loss. The species’s assessment on the Brazilian Red List can be accessed here.
Clarification of the species’s population size is needed to ascertain whether it meets the thresholds for Vulnerable or Endangered under C2a(i). Should the population fall between >2,500 and <10,000 mature individuals, with <1,000 mature individuals in each subpopulation, it would likely qualify for Vulnerable under criterion C2a(i). Comments are welcome to help in the evaluation of this species’s status.
