Poxviruses were isolated from skin lesions of eight silvereyes during 1969-71. In all cases, characteristic virus particles were seen in extracts of the lesions and all isolates produced pocks on the chorioallantoic membrane of embryonated chicken eggs. Comparison by immunodiffusion showed that the viruses were antigenically identical, and that they differed from poxviruses recently isolated from domestic fowls, pigeons and a canary.
