rpHESE birds 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 



thereon being imbedded 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.
