 for life. It is perhaps more gregarious in winter than in

 social instincts, and numbers of pairs very often nest on 

 a small area of ground. The nest is almost invariably 

 made on the ground, either amongst the tall heather on 

 the moors, or in the rank vegetation of the swamps, but 

 occasionally it is said to be built on the ledge of a rock.

 at the base, and more than a foot high. Externally it is

 leaves, and turf, and lined with moss, and, as incubation 

 progresses, more and more thickly with down and 

 feathers, plucked by the female from her breast. This 

 bird is rather a close sitter, and the male keeps constant
