After intensive pilot studies, a large field trial in- volving over 10,000 birds was used to determine the effectiveness of toxoid vaccination of pheasants to limit losses due to botulism on a game farm. Birds inoculated with toxoid suffered a mortality of one- fifth of that experienced by uninoculated pheasants. Trichomoniasis Ten tons of medicated grain was distributed through- out the San Diego area in an effort to combat mourn- ing dove losses attributable to this disease. Although a high degree of success was achieved by this effort, complete effectiveness was not realized inasmuch as not all foci of infection can be found and treated. This work evolved into a co-operative effort on the part of the people of San Diego who feed doves and the department personnel responsible for controlling dis- ease in wildlife. The present approach has been the gradual decrease in the amount of feed put out by the dove feeders so as to avoid large concentrations of birds, thereby limiting the spread of the contagion.
