Trichomoniasis
Trichomoniasis is an infectious disease of birds caused by the single-celled protozoan Trichomonas gallinae. There are several different strains of this protozoan, some of which cause clinical disease, while some of which do not. This disease is also known as canker in pigeons and doves, and frounce in raptors. Trichomoniasis is one of the oldest known wildlife diseases with written records dating back to the 1500s. The protozoan responsible for the disease was not isolated until 300 years later.
