Adult Male in Breeding Plumage. — General colour olive-yellow, 
the rump lighter; breast entirely bright yellow, the under tail- 
coverts of the same colour ; head blue-grey, with a distinct 
white eyebrow ; bill and feet blackish ; iris brown. Total length, 
57 inches ; culmen, 0-55 ; wing, 2-95 ; tail, 27 ; tarsus, 0-85. 
Adult Female. — Duller in colour than the male, and slightly 
browner on the head and back : underneath paler yellow, 
whiter on the throat. Total length, 6 inches ; wing, 3-1. 
Young — Still paler than ~a l the dult female, and with dusky 
spots on the chest ; over the eye a streak of tawny buff ; ear- 
coverts brown ; cheeks and throat dull white, becoming 
browner on the fore-neck and chest. The young birds of 
the Blue-headed Wagtail are scarcely distinguishable from those 
of the Yellow Wagtail. 
Range in Great Britain. — An accidental visitor in summer to 
England and Scotland, principally to the eastern coasts. We 
ourselves once shot a fine male bird in Sussex, near Pagham, in 
May, in company with Yellow Wagtails. Mr. John Hancock 
has certified to the nesting of the species in Northumberland, 
and Mr. Menteith Ogilvie has shown us some birds killed by 
him in Suffolk during the nesting season which appeared to be 
females of M. flava, though the latter are difficult to distinguish 
from the females of M. campestris when their plumage becomes 
worn. 
Nest. — Similar to that of the Yellow Wagtail, and built in 
similar situations. 
Eggs. — Four to six in number, and, as might have been ex- 
pected, very similar in character to those of the Yellow Wag- 
tail. As a rule they appear to be more uniform in tint than is 
the case with the latter bird, the series in the British Museum 
not showing the mottled Warbler-like eggs which are often 
found in a series of those of M. campestris. Axis, 07-075 
inch; diarn., 0-55-0-6.
