ThoughtÂ we would share these excellent images of a Yellow Wagtail Moticilla Flava, so called ‘dombrowski‘. This subspecies is believed to be an integrade between feldegg and probably flava or beema. Images kindly submitted to Cornwall Birding by Adam Boyns. This bird and two White Wagtails were at St Gothian Sands NR, Gwithian on Monday 5th May 2008.
