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.|
|Moult on Right Wing|
