BLACK GROUS. 279 



the under parts of the body are black, varied with 

 spots and stripes of yellow-brown, each feather 

 being also tipped with white : the wings are dusky 

 brown, with transverse bars of chesnut-brown : the 

 secondaries are tipped with brown : the tail is 

 black, tipped with white ; the whole of its upper 

 coverts are varied with brown and black, and 

 tipped with white. 



This bird inhabits only the most northern parts 

 of Europe, Russia, Lapland, Sweden, Norway, &c.; 

 and it is also said to be found in the most northerly 

 parts of Scotland, but I believe without any truth. 

 Very little is known of its habits, which no doubt 

 resemble those of the rest of the genus.
