 Bullfinches are a colourful addition to garden feeders

The BTO’s Garden Bird Feeding Survey (GBFS) was conceived in the late 1960s, to assess the range of birds capitalizing on supplementary foods in gardens and to examine their food preferences. Since the winter of 1970/71,observers have been charting the weekly peak counts of feeding birds countrywide. Today, the survey also provides a check on changes in status of garden species. Bird food and feeders have changed markedly and currently, up to 60,000 tonnes of peanuts and wild bird seed are provided annually in the UK, a bird care facility worth £150–180 millions.
