Objective: To discover beak and feather disease virus (BFDV) genotypes in Australian parrots that might threaten vulnerable and endangered psittacine bird species.

Methods: Phylogenetic analyses of new DNA sequence data from Australian birds including the Rep gene (n=55) and nine whole genomes, were compared with all available published BFDV genomes to assess host- and geographically-based divergence as well as probable host-switch events.

Results: Strong support for flexible host-switching and recombination was detected, indicating active cross-species transmission in various subpopulations.

Conclusion: The data suggested that all endangered Australian psittacine bird species are equally likely to be infected by BFDV genotypes from any other close or distantly related host reservoir species.
