114 MOTACILLID^E. 



Male. Above yellowish green ; underparts, except white chin, bright 

 yellow ; broad white stripe over eye from bill to nape ; head, nape, and ear- 

 coverts Hue-grey. 



Female. Head brownish and duller in colour. Length 6-6^ inches. 



131. Motacilla borealis, Sundevall. The Grey-headed Yellow 



Wagtail. 



Occurs on passage ; passing later than the preceding, of which 

 it and the next can only be considered races. 



Like the last, but head slaty grey and has no eye-stripe, and only the 

 chin is white. 



The race Motacilla cinereocapiUa, Savi, has throat white and partly 

 defined white eye-stripe. I shot specimens in spring, and they were 

 nesting near Casas Viejas in May. 



132. Motacilla rail (Bonaparte). Yellow Wagtail. 



This, the English race of Yellow Wagtail, occurs on passage in 

 spring, but not commonly, and has been obtained at Tangier and 

 Malaga. We saw many about 12th April, 1894, at Tapatanilla. 



Male. Head canary-yellow ; upper parts olive-green ; nape yellowish 

 green ; all underparts, eye-stripe, and axillaries bright yellow. 



Female. Eye-stripe buff ; plumage much less brilliant. 



Young. Eye-stripe and underparts huffish white, with no yellow except 

 a tinge on lower belly. Length 6^ inches. 



133. Anthus trivialis (Linnaeus). The Tree-Pipit. 



According to Favier this Pipit is common near Tangier during 

 migration, crossing the Straits in March and April, returning in 

 October and November. On the Spanish side they are found on 

 passage only : the 9th of April is the earliest date on which I 

 noticed them, but I saw many about the 20th. 



Above clear brown, distinctly streaked with dusky ; spots on breast 

 small ; flanks streaked with black, like the breast ; middle and greater 

 wing-coverts tipped with white, forming a double wing-bar ; light part of 

 outer tail-feather white or smoky white ; axillaries sandy buff. Hind claw 

 curved, shorter than hind toe. Length 6i inches.
