- from Lars Svensson, Nov 2017:
It could be a cross between calcarata and citreola, although strictly of course these are the same species, and you would perhaps prefer to speak of intergrade or an intermediate bird.
But it could also be a cross between calcarata and Yellow Wagtail, but in that case I am a bit lost when trying to suggest a sutable Yellow race candidate.
