'Birdicidal' UK Gardeners

A Sussex University study has shown, that UK gardeners, who are lavish with glyphosphate herbicides, can expect to see fewer song birds on their plots. Regular use of slug pellets also reduces Sparrow populations in UK gardens (https://www.theguardian.com/environment/2023/feb/06/garden-pesticides-british-songbird-decline-study). Some of these chemicals may, of course, directly influence the birds, whereas others probably reduce the local populations of organisms on which they feed. Either way, gardens are more likely to become 'bird friendly', if less 'chemical' approaches to dealing with 'weeds' and 'pests' are employed.
