Our recent good run of birds continued this morning as we reached the Narrows. A stunning male Yellow Wagtail with black ear coverts, a blue grey crown, long white supercilium and mainly yellow throat. Mr. Stansfield muted 'dombrowskii' as a good candidate and this feldegg x flava intergrade certainly looks like a good possibility. However these seem to be indistinguishable from the dark ear coverts form of tschutschensis Eastern Yellow Wagtail, at least in appearance. However the call seemed as flava, not the buzzy Citrine Wagtail type call associated with tschutschensis. So dombrowskii is the more likely, but we'll probably never know quite what he is, but he's a cracker none the less.
