Startling hen murmuration , Culdaff , Ireland .
returned with mother (93) to Davenport's cottage . Made friends with the free range hens last time . Tonight I was walking past their roosting shed when I unexpectedly said out loud , Thank you God . Next moment the shed of hens started to sing , in prefect harmony up and down scales in waves like a jazz choir . It was being done at the volume of gentle cooing but with so many hens at once , the depth of sound was amazing . Never heard anything like it before .
