Prevalence of Mycoplasmal Conjunctivitis

These maps show the prevalence of mycoplasmal conjunctivitis in House Finches from 1994 to 2002. Data are presented for the months of February and November, two periods of high disease prevalence each year. Prevalence is shown as the proportion of days that infected birds were seen by House Finch Disease Survey participants (relative to the total number of days that House Finches were observed). White indicates that no diseased birds were observed, and grey indicates that no observations were reported.
