224 THE NESTS AND EGGS OF BRITISH BIRDS. 



Family ANATID^. Genus Ansek. 



Sub-family ANSERIN.E. 



GRAY-LAG GOOSE. 



Anser cinereus, Meyer. 

 Single Brooded. Laying season, April and May. 



British breeding area : Nearly a hundred years

 and marshes of East Anglia. Its principal breeding area

 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. 

 It is a huge structure, as much as three feet in diameter 

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

 made, according to the locality, of branches and twigs 

 of heather, dead rushes and reeds, dry grass, bracken, 

 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
