Another Sibe Chiff

At the same time I found the 'other' Siberian Chiffchaff at Marston Sewage Works I also came across this bird.  It is distinctly different - its more beige and buff in colouration, without the greyness of the other bird.  The wings and tail, although tinged green, aren't nearly as bright as the other bird, and it also has a light wingbar.  This bird is also much more confiding and spends more time in low vegetation.  It has also been silent on every visit - or at least I haven't seen it call, or been close enough when it has.

On close inspection there is some yellow in its plumage - however this is only visible in the images above.  None of this yellow was visible in the field.

More shots of this bird by Neil Wright can be found on the BedsBirds blog here.

So, should both birds be labelled 'tristis'?  One bird looks good but hasn't called, and the other bird looks good (but more contrasting) and has a slightly strange call. Hmmmm.
