The attractively plumaged Blue-throated Parakeet was formerly common throughout much of southeast Bahia, Espírito Santo, eastern Minas Gerais and Rio de Janeiro, in the Atlantic Forest of Brazil. However, its modern-day distribution is highly fragmented and the species is now mostly restricted to isolated reserves, with the result that BirdLife International treats the species as Vulnerable at a global level. It remains common in a handful of protected areas in northern Espírito Santo and southern Bahia, but over the majority of its range the species is now rare and difficult to observe. This parakeet is an inhabitant of the canopy of lowland humid forest, to approximately 1000 m, but it seems to be able to persist in agricultural areas with sufficient tree cover, such as shade cocoa plantations. Breeding apparently occurs in the austral spring, when 2–4 eggs are laid in a tree-cavity.
