The RSPB recommend the following advice during autumn and winter -
"At this time of year, put out food and water on a regular basis. In severe weather, feed twice daily if you can: in the morning and in the early afternoon. Birds require high energy (high fat) foods during the cold winter weather to maintain their fat reserves to survive the frosty nights. Use only good quality food and scraps.
Always adjust the quantity given to the demand, and never allow uneaten foods to accumulate around the feeders. Once you establish a feeding routine, try not to change it as the birds will become used to it and time their visits to your garden accordingly."
