The eggs of the Pied Wagtail are mostly of a broad oval form, 

 and they are moderately glossy. They are white, greyish-white, or 

 very pale bluish-white, densely speckled or mottled with greyish- 

 brown and underlying lavender-grey. Some specimens are some- 

 what darker than others, but, as a rule, the eggs of this Wagtail are 

 very uniform. A few examples exhibit one or two short black 

 hair-lines at the broad end. The eggs measure from '73 to *87 in 

 length, and from -57 to '63 in breadth.
