Trichomonosis
Trichomonosis is a deadly disease found in a number of garden bird species. It is caused by a microscopic parasite, Trichomonas gallinae, which infects the tissues in the bird's mouth, throat and oesophagus, making it hard for the bird to eat and breathe. While greenfinches and chaffinches has been most affected, Trichomonosis has been found in other species, including sparrow, dunnock, great tit and siskin.
