Some photos of a Siberian (tristis) Chiffchaff caught and ringed at Slapton on 10th Nov by Nik Ward.

The photo to the right shows a nice comparison with a 'western' Chiffchaff (collybita) showing the 'desaturated' buffy/grey and white plumage compared to the bright olive and yellow collybita. Again, like the Clennon bird yesterday, this tristis in bright sunlight shows of olive in the scapulars, mantle and even crown - features that in the past may have resigned it to the abietinus/tristis category, but it lacks the yellow in the body plumage (an underwing shot of the bird showed the yellowy underwing coverts typical of tristis). Tristis usually shows a very dark bill and very black legs with yellow soles to the feet are - shown in this comparison. The supecilium is a dirty buff lacking yellow and the cheeks are slightly warmer buff. 

As with any tristis record it is always good to get call - but many remain stubbornly silent!
