Advice about a possible Mountain Chiffchaff (France) (1 Viewer)

[Gduff]

This bird was observed yesterday on Ile de Sein.

Détail de l'observation - www.faune-bretagne.org

It has some characteristics of Mountain Chiffchaff : mostly brown tint without hint of green or yellow, white throat, black legs, black bill, short PP, buffy-white supercilium ; it never called.
Pictures aren't mine.

What do you think?
Do you know if Common Chiffchaff can have such plumage?

Thank you

Hello Gduff.

tfs this interesting bird!

I cant add anything useful here (although I can detect a smooth tobacco ="tristris" tinge to the ear-coverts).

I just want to link to this interesting "caveat"-thread. Yes, its in german, but I hope nonetheless helpful.

I’ve certainly experienced “Brown Chiffies” at home and further afield over the years, normally last week Sep through to last week in Oct.
As to their point of origin I’m not certain, other than there may well be a link between tristis and Mountain Chiffchaff…wish I knew.

Cheers
