Hedgerows would produce up to 150 times more berries, the food of many declining birds such as the song thrush, if they were cut every three years instead of every year, scientists said yesterday. A full farm-scale evaluation of the effect of hedge-cutting frequency on hawthorn berry yields has pinpointed the tractor-mounted flail cutter as a likely culprit in the decline of the song thrush on farmland over the past 30 years. Number have fallen nearly 70 per cent.
