broader on the second, and extending over part of the outer web ; 

 the next narrowly edged with white; upper tail-coverts like the back. 

 The female has a white superciliura; the head and crown 

 duller, mixed somewhat with greenish later in the year ; the chin 

 is white, and the throat a yellowish or buffy-wliite ; breast and 

 under parts pale-yellow ; back greyish-brown. 



The Grey-headed Field Wagtail occurs both in the Deccan 

 and in Sind. It has apparently been overlooked in Guzerat and 

 Raj pu tana. 



They are difficult birds to deal with, and Jerdon did not discri- 

 minate the two last species. 



The following key by Mr. Brooks will assist greatly in helping 

 collectors to discriminate the three species : 

 B. /lava. Grey head, broad white supercilium, grey and white 



cheeks. 



B. cinereocapilla. Dark-grey head, supercilium absent or else 

 very narrow and white ; often only half a supercilium 

 behind the eye ; cheeks a dark slate color or almost 

 black. This dark cheek is the well marked peculiarity of 

 the species. 



B. melanocephala. Pure black head, with very rarely indeed 

 a supercilium, and then very narrow, like a thin white 

 thread. 

 The black head is a good distinction.

THE YELLOW-HEADED WAGTAIL. 



Length, 6'5 to 7 ; extent, 10 ; 5 ; wing, 3'25 to 3'5 ; tail, 3'5 ; bill 

 at front, 0'48. 



Bill black ; irides brown ; legs black. 



Entire head, chin, throat, breast, and under surface, bright 

 yellow ; back, rump, and upper tail-coverts dark-brown, nearly 

 black ; lesser wing-coverts dark -grey ; median and greater wing- 

 coverts dark-brown, margined and tipped with white ; the ter- 

 tiaries broadly margined with white ; primaries and secondaries 

 on their outer webs, dusky on their inner, and with whitish 

 margins ; tail dark-brown or black ; the feathers very narrowly 

 edged with greenish ; the four outermost white, except a dusky- 

 brown margin on the inner web for three-fourths their length. 



In winter the adult is light ashy-grey above, the nape and 

 sides of the breast darker ; head and under surface yellow, oli- 

 vaceous on the flanks ; primaries dusky, edged with greyish-white 

 on their outer webs ; secondaries dusky ; tertiaries darker, broadly 

 margined with white ; wing-coverts brown, broadly tipped with 

 white, forming two, conspicuous wing-bands ; lower tail-coverts 

 albescent or very pale-yellow; tail as in the breeding plumage.
