During the fantastic Ely Wildspace Bioblitz last weekend this Chiffchaff singing along Kiln Lane during the Saturday morning Dawn(ish) Chorus walk drew attention to itself. Initially I thought it was two birds singing but I was able to confirm, from observation, that it is the song of just one bird. The syncopation of the song is unusual, earlier in the season the exact same song posts were used by a standard singing bird, is it the same bird with a variation over time??
