The finches include species in Geospiza, Camarhynchus, and Platyspiza genera, and mockingbirds include all four Mimus species in Galapagos. Prevalence is the proportion of specimens displaying lesions that could have been caused by the Avipoxvirus, prior to the testing of a subset of these specimens.
