a stonechat and a new word

This is a Siberian stonechat or also known as an Asian stonechat (Saxicola maurus).

It is also a burb.

But our word for today is Palearctic, as in what you can say at a posh dinner party.... "oh yes, yes, this particular stonechat, it breeds in the East Palearctic realm". See how many heads nod in agreement, but do they really know that the Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth, stretching across all of Eurasia north of the foothills of the Himalayas, and North Africa.
