Trichomoniasis - Wild Dove Disease
Trichomoniasis is a disease that affects mourning doves and other wild birds. It is not transmissible to humans. It is caused by a microorganism that exists naturally. Doves are particularly susceptible to this disease and outbreaks may be seen in late winter/ spring. When this occurs, birds commonly die at or near feeders or water sources, where the disease can be easily transmitted between doves.
Visit the National Wildlife Health Center Field Manual of Wildlife Diseases for more detailed information.
Contaminated feed is suspected to be a significant source of disease transmission. Therefore, fresh feed should be placed in bird feeders frequently, if it is practical. Platforms and other surfaces where feed may collect, including the area under feeders, should be frequently decontaminated with 10 percent solution of household bleach in water, preferably just prior to placing clean feed in the feeder.
