Disease and garden birds
It is known that the transmission of disease between individuals tends to be increased where birds gather together in large numbers and this may go some way to explaining why some species may be more susceptible than others.
Anecdotal evidence suggests that some bird species may be more susceptible to disease than others. Certainly, Greenfinches, Chaffinches, Siskins, House Sparrows and Collared Doves appear to be the most commonly reported victims of diseases. This may, in part, reflect the gregarious nature of these birds and their tendency to feed in flocks.
Information on diseases and other forms of mortality in garden wildlife is being collected through Garden Wildlife Health.
