Hi Abdulla,

As the bird is already white-headed by the first week of February, I reckon it has its origins at the steppe, rather than from the arctic tundra populations.
The relatively long, white tongue on the underside of P10 probably best match to barabensis or birds from the eastern cachinnans breeding zone like the ones found in eastern Kazakhstan, see:
