Message: <blockquote data-quote="TringBirder" data-source="post: 1809377" data-attributes="member: 43827"><p>It is my understanding that all races of Yellow Wagtail (Western and Eastern species) can have grey-and-white variant but the eastern sub-species show a greater propensity for this. Feldegg possibly shows greatest propensity as females regularly have greyish upperparts. This bird obviously must be 1st summer or older so bill colour and some head features mentioned previously become irrelevant. There is currently a female Yellow Wagtail at Tring Res (possibly breeding nerarby), that resembles this bird in the greyish upperparts but its call doesn't suggest it is an eastern bird.</p></blockquote><p></p>
