Yellow Warbler - first-winter possibly male - Portland Bill, Dorset 21st August 2017 (1 Viewer)

A selection of photos of the first English record - 6th British record & 11th British & Irish record.

I am inclined to age as a first-winter on the basis of the pattern of the outer tail-feather according to page 137 of Pyle - Identification Guide to North American Passerines - and the brown primary coverts (as opposed to black) according to both Pyle and page 469 of Stephenson and Whittle - The Warbler Guide.

The undertail coverts were strong yellow and so were the underparts on most occasions. The colouration of the underparts and the greenest of the upperparts is affected by adjusting the photos to deal with the fact that they were heavily back lit in low light. Reliable sexing does not appear possible but maybe a male as a result?

Four sets of five photos with the last containing the photos showing tail feather pattern.

All the best

Paul
