BLACK GROUS.

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.
