Warbler ID, UK (1 Viewer)

Hello,

Could anyone help me ID this?
From the Malvern Hills today.
It was in a small tree at edge of playing field next to a wood.

Still learning about warblers....I read the beginners guide post.
Of the common ones, the only ones that seem possible are willow, garden or chiffchaff.

It was making a monotonous short sound, different to the garden warbler sounds I find online, closer to the "call" section of the willow warbler I can hear on www.british-birdsongs.uk. But no strong white supercilium here so does this mean not a chiffchaff or willow warbler?

Many thanks!

It's a Chiffchaff, one of the 3 you considered. Note the dark legs, the short primary projection and relatively dull colours.

The "song" of the Chiffchaff is more a repetitive series of notes than an actual song, as far as I am aware; which fits in well with your description "monotonous".

It definitely didn't vocalise the chiffchaff song... its so distinctive...
This was more monotonous and larger intervals between notes.
But could have been the "call", or "alarm call" listed here...

Though I would still say it was closer to the willow warbler "call" on that website to my memory. But maybe that's my memory playing tricks on me.

Is it normal that the supercilium is not so pronounced?
Is this to do with plumage at this time of year or something?

Thanks!

It's a perfectly normal Chiffchaff. Another feature that is diagnostic is the number of emarginations on the primary feathers: CC have emarginations up to P6, whilst on Willow W they reach P5 only. This is well visible on your 1st pic.
