A walk around Clennon this afternoon produced 6 'collybita' Chiffchaffs and one non-calling possible tristis (Siberian) see pictures. Not as black legged as many and perhaps a hint of yellow in supercilium (I could not pick this out in the field so perhaps reflected light from leaves?). Interesting to see how plumage colour varied when photos taken in shadow, overcast and direct sunlight.
