MOTACILLA FLAVA. (linn.) 

 Yellow Wagtail. 



The eggs of the Yellow Wagtail, as will be seen by the 

 Plate, very closely resemble those of the Grey Wagtail, so 

 much so, that either of the figures may be considered as 

 varieties of the other ; those of the Yellow Wagtail often as- 

 suming the colouring of Fig. 2 ; whilst those of the Grey 

 Wagtail are frequently of the deeper hue of Fig. 3 ; the 

 nests resemble nearly those of the other two species ; the eggs 

 are, in number, four or five ; but I have known them lay as 

 many as six.
