Plummeting temperatures present challenges for birds as supplies become scarce, but the experts have revealed the one food mistake that could drive robins away from your garden this October.

According to Jaymi Heimbuch, a specialist from Better with Birds, feeding robins bread gives them a false sense of fullness and can cause digestive issues.

"It's basically junk food for birds — fills them up with no nutritional value," Jaymi told The Express.

Like ducks, bread contains no necessary proteins and won't provide birds with the varied diet they need to survive harsh winters. Throwing a slice of bread on the lawn might seem like an easy bird-feeding win, but it can actually cause more harm than good.

High-energy foods you should offer instead include suet, sunflower hearts and peanuts, which are particularly valuable for garden favourites like tits, finches and starlings.

"Autumn is an important time for feeding wild birds, as some species will prepare for long migrations and need extra calories to fuel their journey, while others stay behind and depend on reliable food sources as natural supplies start to run low," says Richard Green from Kennedy Wild Bird Food & Pet Supplies.

"Feeding birds with high-energy foods now gives all birds the best chance of staying healthy through the colder months."

As well as monitoring the food you serve, it's also worth cleaning bird feeders to prevent a grime build-up.

"Using hot, soapy water or a wildlife-safe disinfectant helps remove mould or spoiled food left over from summer," adds Richard.

And don't forget: "Position feeders in sheltered spots to protect against wet and windy weather, and consider adding extra feeders to spread out visiting birds and reduce crowding."

You'll keep your feathered friends happy in no time.
