Feeding the birds is a joyful pastime for many homeowners, but bird conservation and protection charity RSPB has issued an urgent warning about bird feeders and deadly diseases.

The charity has removed flat bird feeders from its website, following information that may contribute to the spread of fatal diseases among UK birds, particularly finches.

Flat bird feeders have been linked to spreading diseases such as trichomonosis, a deadly illness for birds caused by a parasite. This disease is thought to be responsible for the decline of the greenfinch population in the UK.

Diseases such as trichomonosis can be easily spread via flat bird feeders if an infected bird drops some food onto the flat surface, leaving it behind for a healthy bird to pick up.

"We know so many of you love feeding your garden birds and some bird species really do benefit from us putting out extra food for them, especially in winter," the RSPB says.

"However, there is increasing evidence that for other birds there can also be negative effects such as the spread of disease, especially among finches."

A spokesperson for the charity continued: "As a precautionary measure, whilst we await the findings of the review, we have suspended all our bird tables and related products, table mix and table mix extra, window feeders and feeder guardians with trays, from sale.

"This is because there is evidence to suggest that some birds, particularly finches, can be more exposed to disease when fed on flat surfaces like these."

Responding to the RSPB's decision, Jon Carter from the British Trust for Ornithology, said: "Research demonstrates that there are both pros and cons to feeding the wild birds that visit our gardens.

"We understand the concerns that people may have about possible negative effects, particularly those linked to the emergence of infectious diseases such as finch trichomonosis.

"It is the evidence from this research that shapes the advice that we provide on feeding, and we will continue to update this advice as new evidence comes to light."

However, that's not to say that gardeners can't still feed birds, which is particularly important in winter when food is more scarce.

Opting for a hanging feeder is more hygienic and reduces the risk of spreading diseases by preventing cross-contamination of food by dropping food more gradually.

You can also scatter food for birds on flat areas in the garden, such as decking, patios, and driveways, but it's essential to keep these areas clean and rotate them regularly to prevent the spread of disease. Homeowners should also regularly clean feeders and birdbaths to keep feathered friends safe.
