Siberian Chiffchaff? (Croatia) (1 Viewer)


Luca Boscain
I photographed this bird few days ago in central Croatia and I instantly called it "Siberian Chiffchaff". I tried to induce the voice with the playback, but there was too much noise of water and I couldn't hear any call. Now it came up that it might be the first Siberian Chiffchaff ever for Croatia. I know that without the call is almost impossible to tell for sure, but is there anybody that doesn't agree this is most likely a tristis??

It is much depending on how conservative you are calling a bird a tristis. Chiffchaff is a very variable species after all. Can't imagine that this would be enough to claim a national first...

I am not a specialist, but I spent some time looking and reading about trsitis :).
So focusing on the arguments:
1) gray-brown (not greenish) mentle, head- ok
2) white- buff supercilium, eye-ring - ok
3) generally gray-buff bottom -ok
4) buff: face, sides of the breast, flanks - ok
5) no yellow shades except underwing covers - ok
7) rump brighter than mantle - ok
8) eye-strip: blackish at the front, and in the color of the head behind the eye - ok

1) supercilium brighter at the front, smoothly turning into the color of the head behind the eye - no (?)
2) underwing can be yellowish (buff-yellow) - but only under the shoulder, possibly pale lemon underwing covers at the front of the wing, but the covers should be generally dirty white - too much yellow (?)

Visually it looks like a perfect tristis to me. The fact that the yellow underwing coverts contrast so sharply with the rest of the bird just shows that green/yellow pigmentation is more or less completely lacking elsewhere in the plumage. In addition to the features highlighted by Michal, note the black legs.
Of course if the Croatian committee requires a sound file for acceptance, and it’s indeed likely to be the case, you’re doomed...
