bo ob 
The eggs of the Yellow-headed Wagtail are so similar in general 
character to those of M. boarula of the commoner type, that they 
cannot be separated from them. They measure from 72 to ‘82 in 
length, and from °56 to 6 in breadth. A very small example 
measures only °66 by ‘5, and is one of a clutch of six eggs.
