Beautiful little bird. There have been a reasonable number this year - Meidad Goren saw three this morning in Nafcha alone - let's hope they follow the increasing westward trend as seen in the UK.
And now for some controversy. Cetti's Warbler - looks like a classic Cettia cetti nominate.
Ten tail feathers - the only species with this number I think.
Unusual enough for Sde Boker but this individual from 10 days ago looks very different. Note the lighter, greyer tones and, strikingly, the white eye stripe. Cettia cetti albiventris?
The 'ventris' looks more 'albi' than on the standard Cetti's and without the white feather tips.
If this is C.c. albiventris this would be a very rare migrant from Kazakhstan so all comments welcome.
