Swan Mum of the Year
A mother mute swan attends to her cygnets at Abbotsbury Swannery, Dorset, UK, in May. The arrival of mute swan cygnets is traditionally seen as the start of summer, and it’s said the Benedictine monks who owned the swannery between about 1000 and the 1540s believed the first cygnet signalled the season’s first day.
