Always a red letter day in my nature calendar, today produced the first singing Chiffchaff back in South Cardonald. Previous years' first dates have been as follows: 20/03/20; 25/03/19; 01/04/18; 29/03/17; 28/03/16; 01/04/15; 25/03/14; 13/04/13; 31/03/12; 02/04/11 and 29/03/10. The other notable sighting of the day was of an unprecedented ten Bullfinches feeding together on the back garden feeders and on the grass below.
