Male in spring plumage (Manila, April, 1904-). Above olive-yellow; 

 tail-coverts brown edged with olive-yellow; top of head and nape cin- 

 ereous, the ear-coverts a little darker ; lores and space under eye blackish ; 

 a wide line from nostril over eye to nape white; sides of neck and of 

 chest olive-yellow; chin white; remainder of under parts canary-yellow, 

 or light lemon-yellow, with some obscure dusky spots on chest, crissum 

 palest; thighs ashy gray; wings dark seal-brown, many of the feathers 

 edged with yellowish or huffy white; tips of greater and median coverts 

 forming bars; two outermost pairs of rectrices nearly all white, the 

 others seal-brown with narrow olivaceous edges. Length, 165; wing, 

 81; tail, 72; culmen from base, 15; tarsus, 25. 



The female is duller in color; the upper parts browner and the under 

 parts paler yellow. A female from Calayan Island measures : Wing, 74 ; 

 tail, 70 ; culmen from base, l;> ; tarsus, 25. 



Winter plumage. Most of the specimens taken in the Philippines 

 have the crown, sides of head, and upper parts dull brown, sepia to hair- 

 brown, at times with traces of olive-yellow on the back; the long white 

 Hiipercilium is always present; the under parts are mostly white, chest 

 more or less dusky and with spots or irregular patches of yellow. 



"Much less common than M. melanope. Three males average: Length, 

 1(59; wing, 80; tail, 76; culmen, 17; tarsus, 25; middle toe with claw, 

 20.5. A female measures, length. 165; wing, 77; tail, 73; tarsus, 24; 

 middle toe with claw, 21.5. Legs, feet, and nails dark brown to black; 

 bill black, except base of lower mandible which is gray." (Bourns and 

 Worcester MS.) 



At times I have found large flocks of this yellow wagtail in the vicin- 

 ity of Manila, but it is usually less abundant than the gray wagtail. 



* Philippine specimens of this genus may be the recently described Budytes 

 flavus alascensis but no specimens of that race are available for comparison.
