Thanks to Neil Wright, I finally got to hear the remaining Siberian Chiffchaff sing yesterday morning. And it sounds like like it should for a tristis. Take a listen:
But there is no doubt this wasn't a 'classic' bird, at least in my eyes. When it first arrived it looked good (see above) but you would have walked straight past it if you were only 'listening' for Siberian Chiffchaffs. Take a listen here:
The calls represented here were typical of what it was giving constantly. Interstingly since first picking it up in early December I have hardly heard it call in all the visits I have made over to look at it. However it called several times yesterday and I managed to get two snatches on my Remembird:
None of these calls are the true tristis 'peep'. They are virtually all a clear rising 'wheep' just like collybita. The two calls recorded yesterday are actually much closer to a true tristis call but still aren't really flat, as you can see in the sonogram above. So where does that leave us?
Well, it looks like a tristis, and it sings like a tristis, but doesn't really call like a tristis. Is it a tristis? I think so. This bird is a prime candidate for having some DNA work done so we'd know once and for all, that tristis can call just like collybita.

Another interesting Chiffchaff. This one was at Broom GP. I initially saw two birds in the willows - one dingy grey collybita type which was calling constantly, and then this bird. I hadn't noticed it until I tried playing tristis song at the collybita bird (just to see if it would react more than anything else), and this bird popped out from the bottom of some willows and started flapping its wings and bouncing around the branches above me. Unfortunately this bird remained silent throughout.
Plumage wise this is an odd bird. From a distance it looks buffy and brown, with the only real green around the wings and tail. Up close the green is much more evident, especially around the mantle, flanks and in the supercillium. The two chiffchaffs in this clump also act differently - the collybita is often much higher up in the top third of the willows, but this bird is usually at the very bottom - usually in the bottom two feet, just above the water.
To say that chiffchaffs do my head in is an understatement! As others have said, its redpolls all over again...
