The eggs of the Yellow Wagtail are of much the same general 
character as those of J. boarula, but are, as a rule, of a rather 
darker colour. The eggs of the two species cannot, however, be 
separated with certainty from each other. Specimens measure 
from *69 to °82 in length, and from *51 to °6 in breadth.
