 The parrots are particularly threatened by the fatal psittacine beak and feather disease virus (BFDV), and there have been suggestions that a diet heavy in yellowwood fruits greatly reduces the symptoms, although this has not been empirically investigated.Their habitat is being reduced by logging and modification of African yellowwood trees, in particular the loss of old trees and dead snags with suitable nesting hollows.The provision of nesting boxes has had some success and offers some hope for increasing the proportion of breeding individuals.
