Well, the results of the Big Garden Birdwatch are in and once again there is a drop in the number of insectivorous birds. I remember the days before refrigeration was common and agricultural pesticides had not reached the level of sophistication of today. On warm days, flies were a frequent annoyance. For car drivers, it was worse as flying insects committed harakiri on their windscreens
I can foresee the day when genetiaally-modified flies wll be relesedj to keep a vaible populaton of songbirds.
