Avian bornavirus (ABV) was discovered recently in parrots with proventricular dilatation disease (PDD), a fatal neurological disease. Although ABV has been shown to be a causative agent of PDD, its virological characteristics are largely unknown. Here we report the detection of ABV genotype 5 RNA in an Eclectus roratus with feather picking disorder (FPD). Interestingly, although the bird was persistently infected with ABV5 for at least 8 months, it had no clinical signs of PDD. Although it remains unclear whether ABV5 is associated with FPD, these findings raise the importance of epidemiological studies of birds with diseases other than PDD.
