The sound is stored here: BIRD SONG.
Addendum:My grateful thanks to Joe of Joe's Wildlife Garden (who found me a very similar sound file) and Frank of The Early Birder who both came up with it being a Chaffinch. It seems to be a variation of the Chaffinch 'rain song'. I had filmed a Chaffinch making its rain song in my post Bird Behaviour back in June but by comparison that one sounds as though it had laryngitis.
A few days ago I spotted this web under the bird bath part illuminated by the Sun.
