Recent research show that it’s important to adjust what garden birds are fed during the summer and autumn months when there’s a higher risk of disease spreading. 

From 1 May until 31 October, it’s advised that wildlife lovers should pause filling their bird feeders with seeds and peanuts to prevent too many birds gathering in one place. 

During this time, the risk of trichomonsis outbreaks is greater, there is higher availability of natural seed and little evidence of the beneficial effects from supplementary feeding.

The updated guidelines recommend feeding seed and peanuts from November to April, when the benefits to birds are likely to be greatest, although it’s still fine to keep offering small amounts of mealworms, fat balls, or suet year-round. 

Regarding safe feeding, it is worth remembering that just one infected bird can turn a busy feeder into a disease hotspot. 

To help keep birds healthy, hygiene must be prioritised with feeders being cleaned weekly, moved around to prevent the build-up of contaminated debris underneath which should be immediately cleared up. 

Drinking water should be changed daily - only tap water should be used and bird baths should be cleaned weekly. 

If possible, flat-surfaced feeders including bird tables should ideally be retired as research has confirmed that there’s a higher risk of the disease spreading on flat surfaces, where contaminated food can collect for other birds to eat.
