What bird is this?

Hi everyone,

We had a visitor on our patio this afternoon (in South West Wales) - but we're a bit stumped about what species this bird is!

Black legs/feet, black beak, and a fairly distinct cream/white band across its face from eye-to-eye.

It's bigger than a robin or sparrow - more like a small Starling in size.

Could be a juvenile as it seemed to behave more like a fledging than an adult?

Can anyone help ID for us?

Thanks in advance!
