Morocco: Which bird is this? (1 Viewer)

[Holger]

This bird is from Morocco, Erb-Chebbi region, April 2023. Which species is this?

Hello Holger,

evident olive/greenish tones in the upperparts and wings and clear yellow in the supercilium are bad for a Sylvia Warbler, therefore its either a Common or an Iberian Chiffchaff.
It is no Western Bonellis Warbler which has cleaner/purer white underparts and even brighter green tones in the wing and I dont a Willow Warbler vibe here (do you have more pictures?).

But which? Maybe its possible to take location and date into account?
Do you have more pictures? This one is excellent and more pictures and comments could well turn this into a reference thread. Ein Träumchen you know and this came into my mind again: New to Europe, Chiffchaff? Monfragüe, Spain

Anyway: Tfs!

I have just one additonal picture from this bird. Location is southeast of Mezane and east of Dar Kaoua, 15th of April 2023.

Hello again Holger,
thanks for the new picture!
Difficult to exclude a Willow Warbler now= I think it is one.

I hope for more comments. Thanks!

Willow Warbler for me. P6 has no emargination, primary projection quite long, supercilium fairly contrasting, etc, also bill quite robust for either Chiffchaff.
