Thanks Paul for sharing some more nice photos. The Warblers a bit of a nightmare and I understand you might have other behavioural and structural characteristics that may have pointed towards (?Western) Olivaceous Warbler Iduna pallida. Was there any chance this might be a Booted W I caligata?
The reason I wondered was the front part of the upper edge of the supercilium seems to be dark edged, the bird appears rather compact and the legs seem rather pale with dark feet(that's why they are called 'booted'!)
Always difficult with limited views but you did well to get these images.Details of the bill tip and primary projection would be helpful.
Attached is a Western Olivaceous from the greek island of Lesvos digiscoped 5 years ago - interestingly its leg and feet appear to be different colours !
With kind regards,
Eric

Eric,
Thanks for your views on the ID of this difficult bird (to me at least). I have re-examined all my relevant photos & compared them to your photo of Olivaceous (it helps me a lot). As you pointed out correctly, the bird in my photos got a longer & darker supercilium, a smaller bill than a Olivaceous, so it was a Booted Warbler indeed. Thanks again.

This amazing little bird built its nest in a very professional way! When it returned to the nest, it didn't simply jumped in. It spent a lot of time on touching up around the critical connection point between the tree branch & the nest. When it felt the nest was safe enough, it then entered the nest & enjoy!
