feed upon the tender tops of heath and other plants. 

 Some of them are confounded with the Grous, and

 ground. Perhaps this genus would bear division, 

 the two last species having the two middle tail- 

 feathers considerably elongated and pointed j their 

 manners are also slightly different.
