Just a reminder to wash your bird feeders before putting them out. They can harbour bacteria, that can be lethal. According to the BTO the finch population has declined by 95% since 1995. One contribution to this is a disease called, 'trichomonosis' which is a microscopic parasite. It's more active in the autumn, and is a slow death for the bird, they struggle to swallow food and drink.
