140 PIED WAGTAIL 



about three and a half internally, and is composed of stems 

 of grass, leaves, small roots, twigs, and moss, lined with 

 wool, hair, thistledown, the finer grasses, or feathers, or any 

 other such soft substances, all somewhat rudely, or rather 

 loosely, put together. The same situation is resorted to 

 year after year for a long time, the nest being often placed 

 either in or very near to the same spot. 



The eggs, four to six in number, of an elongated oval 

 form, are light grey, or greyish or blueish white, sometimes 

 tinged with yellowish or greenish, spotted all over with grey 

 and brown. They vary, however, very considerably both in 

 size and colour.
