Male Chaffinch
Unfortunately this poor bird has a virus called Papilloma virus also known as "tassel foot" this is a contagious virus to other species of bird and is spread through infected perches, feeders and bird baths, untreatable in the wild it is recommended that feeders, perches etc are cleaned and disinfected and are removed for a couple of weeks or so to make birds disperse for a while to help alleviate the spread of the disease locally.
