 Cley.
Pale green in wing and tail edging.
Brown tea stain bleeds down from ear-coverts to breast sides.
Greyish brown crown, mantle and wing-coverts.
Call: This sighting of the Siberian Chiffchaff was confirmed by the bird calling on two separate occasions.
The call being a flat monosyllabic call ‘ weet’ and of a higher register than Chiffchaff.
It was useful that three other Chiffchaffs were in the area to provided comparative calls set against the Siberian Chiffchaff
and providing further confirmation of call differences. Dr M Davies
