The Eurasian Jay (Garrulus glandarius) has 8 racial groups (33 subspecies in total) whose characteristics vary from a streaked crown or a black crown, a white face, a reddish face, either a white forehead or not, either a white wingpatch or not, etc.
This is the eastern Europe/Middle-East race of the Eurasian Jay (Garrulus glandarius atricapillus) which is different to the western European variety (Garrulus glandarius glandarius) in that it has a thicker bill, a white forehead and a black cap (not black streaks).
