Description
A male Chaffinch, Fringilla coelebs showing signs of the disease Trichomoniasis aka Canker.
This disease is caused by Trichomonas gallinae, a single-cell parasite. It causes necrosis of the mouth and crop, so that the bird cannot swallow. Regurgitated food causes the disease to spread to other birds via saliva.
Birds affected by the disease are puffed up and lethargic, moving food in their beaks and eventually dropping it.
Trichomoniasis is most prevalent in Finches, especially Greenfinches, where it was first recorded in 2005, causing a 20% reduction in the UK's Greenfinch population in 2006 alone.
It is called canker in pigeons and doves and fround in raptors.
