Missed two years of Estonia, I am happy to welcome it come back to my collection. As before, it still 'Bird of the year' series and Grey Partridge to be selected as bird of the year. Of course it appears on the stamp.
Grey Partridge is quite common the northern Europe to middle-Asia, sometimes can be found in Xinjiang, the far north-west of China. But it have been specially introduced to Canada and USA for game bird, thus now quite common in North America.
This cover specially thanks to philatelic office of Estonia, their staff are professional and kindly help senior collector, I am regards their works.
