This Crane visits all parts of the fur-countries in summer up to the shores of 

 the Arctic Sea. Its eggs are oil-green, irregularly, but rather thickly spotted 

 with yellowish-brown and umber ; the spots confluent and dark on the thick end. 

 Its flesh is good food, resembling that of the Swan {Cygnus buccinator) in flavour.
