THE RSPB is warning that humans are not the only ones who will have a shock to the system as temperatures fall.
Garden birds will also have a rude awakening and will have to start relying on the goodwill of gardeners and householders.
The bird charity has been inundated recently with the kind of calls usually received during the summer. Mild autumn weather has meant late sightings of summer migrants, late broods for birds like blue tits and empty feeders.
The RSPB is asking people to leave food and water out in their gardens.
Tom Waters, RSPB wildlife adviser, says: “The sudden change in weather almost certainly means that garden birds will start to turn up in gardens en masse once again, hoping to find supplementary food and water.
“We may not be in the bleak midwinter just yet, but if the temperatures dip significantly, as is predicted, it will instantly become a tough battle for survival for lots of birds.”
The RSPB suggests seed mixes, peanuts and fat balls, along with leftovers like grated cheese, porridge oats, soft fruit and cooked rice and pasta.
