Hi,
I took this shot at RSPB Snettisham in May, but I am struggling to decide if it's a chiffchaff or willow warbler (or something else). I think chiffchaff, but any help IDing would be great.
Thanks
I think willow warbler, there seems to be a lot of white on the chest and lower body.
I good indicator is the call, a chiffchaff has quite a distinct call sounding like it is calling its name, "chiff-chaff-chiff-chaff"
regards
John
