Some 87 per cent of 936 people surveyed who feed birds in their garden said they would not cut back this winter as a result of pressure on household budgets.
Gardman marketing director Jane Lawler said: "It appears that although consumers are cutting down their expenditure in many areas, feeding the birds is one of those activities that is unlikely to be curtailed."
She added: "This underlines the importance of maintaining bird feed and feed equipment in stock and if we get a particularly cold spell we would expect sales to peak dramatically."
Recent Garden Centre Association figures showed that pets and aquatics, including wild bird care, sales fell 12 per cent in 2011 - the worst performing sector measured.
- 44 per cent of 18-24-year-olds feed birds and of those 80 per cent will not change their habits.
- 80 per cent of over-65s feed birds, with 90 per cent continuing.
- People in central England are most likely to cut back on feeding birds (12 per cent).
