Siberian Chiffchaff

Found this cracking SIBERIAN CHIFFCHAFF at Sherborne Sewage Works during the weekend giving amazing close up views. Heard & seen giving classic "tristis" calls and some subsong. Also present include 15+ Colybita Chiffchaff, 2 Firecrest, 15 Goldcrest, Bullfinch, 8 Siskin, Sparrowhawk, Kingfisher, Grey Wagtail and 30+ Pied Wagtail.

Took a trip to Chew Valley Lakes to look at the large Gull flocks present and saw this putative Heuglin's type Lesser Black Backed Gull. Thoughts on this bird may be a hybrid Herring X Lsr Black backed Gull rather than Heuglin's but it shows some very interesting features. No sign of any Ring-billed Gulls, but 150+ Lesser Black backed Gull, 150+ Common Gull, 11 Scaup and 2 Black-necked Grebe other birds of note.

Short leggs, light slate grey mantle& wings, heavily streaked head, neck & flanks

Obvious white tail with 2 distinct markings, slate grey wings and dark streaked head giving hooded appearance

Heuglin's type Gull

Large white tail, dark primaries & pale grey mantle

The heavily streaked head, neck & flanks very distinct here.
