Late summer marks the end of breeding season for most birds, when many begin a natural process known as moulting. With their duty done and the demands of nesting behind them, they begin shedding old or damaged feathers and replacing them with a fresh set.
During moulting season, which typically takes several weeks, birds become shier and more cautious as the momentary loss of feathers affects their ability to fly – making them more vulnerable to predators. This means you may notice fewer birds visiting your garden at this time of year.
Robins are among the first birds to moult and, thanks to their famously inquisitive nature, they’re also one of the species you’re most likely to spot mid-moult. Throughout August, you may see a few rather dishevelled-looking robins with patchy plumage or even a bald head.

They may look a little worse for wear, but there’s usually no cause for concern, as a bird-feeding specialist at Kennedy Wild Bird & Food Pet Supplies explains.
“Growing new feathers uses a lot of energy and protein, particularly after the demands of breeding and raising chicks, so moulting can be a taxing period even though it is completely natural,” Richard Green tells us.
If you’d like to give your favourite garden birds a helping hand while their new feathers grow, there are a few simple things you can do to support them through moulting season.
5 ways to help robins during their annual moult

1. Provide protein-rich feed
“Mealworms are a good choice during the moult because they provide protein to support new feather growth, while fat and suet can offer extra energy in cooler or wetter weather,” says Richard.
There’s one caveat, though. “Seeds and peanuts should be paused until the end of October to help limit the spread of diseases such as trichomonosis, so mealworms are a better option in late summer,” he warns.
2. Offer a safe feeding spot
Because moulting can make birds less agile, it’s vital to provide a safe feeding spot. “Robins often feed on or close to the ground, so placing food near shrubs gives them quick access to shelter,” the expert advises.

3. Don’t forget about fresh water
“Fresh water helps robins drink, bathe and keep new feathers in good condition during the moult,” Richard tells us. “Give birds a shallow bird bath no deeper than around 5cm, making sure the water is changed daily and the bath is kept clean.”
4. Keep feeding and drinking areas clean
Maintaing hygiene around feeding areas is crucial. “Feeding areas can bring birds into close contact, which increases the risk of disease spreading,” Richard explains. “Clean feeders weekly with hot soapy water, remove droppings and old food and only put out as much as birds are likely to eat in a day.”
5. Don’t mistake moulting for illness
Finally, don’t worry if you see a rough-looking bird. “Patchy, uneven or dull-looking feathers and quieter behaviour can simply be signs of the annual moult rather than illness,” the expert shares.
“Birds often spend more time sheltering while replacing their feathers, which can make them seem unusually withdrawn or scruffy for a short period.”
