'HpHESE birds, which breed in the Orkneys, Shetland, and 

 1 Hebrides, as well as a few places on the mainland of 

 Scotland, build both separately and in companies twenty or 

 thirty pairs together. They make their nests on some raised 

 part of a marshy place, or the top of a moor waste ; the 

 heath, moss, or grass being depressed into a nest. 



The eggs are two in number. They are laid early in 

 June. They are of an olive-brown colour, spotted with 

 dark brown.
