|Siberian Chiffchaff - Calling a single mournful "peep" note.
Warm brown ear coverts, strikingly white underparts, dark bill and green mostly confined to wing and tail feathers
|Common Chiffchaff - Not the bird seen today, but a good comparison
|Probable Siberian Chiffchaff - Not heard to call, but still fairly striking with bright white underparts.
Possibly too green on mantle but nowhere near as striking green as Collybita
