For singer and songwriter Kitty Macfarlane the natural world and the landscape around her provides the inspiration for her work, especially when she takes a sound recorder out with her to record bird songs. Or takes part in an eel project, with an ever present grey heron never far away.

Kitty continues her selections from the Tweet of the Day back canon.. You can hear all five episodes chosen this week, and further thoughts from Kitty on how she first saw a bittern recently via the the Tweet of the Week omnibus edition, which is available to download via the Radio 4 Website.
