BEITISH WARBLERS 



centre, and this centre is most conspicuous on the crown 

 and back, fainter on the long upper tail-coverts, and almost 

 disappears on the back of the neck. The upper surface of the 

 tail is of the same hue as the upper parts, but of a slightly 

 darker brown, narrowly edged with lighter olive brown, and 

 marked with faint transverse bars — the shaft of the feathers 

 being dark reddish brown. The lores are olive grey, a super- 

 ciliary streak, which disappears behind the eye, is a whitish 

 olive yellow ; cheeks and ear-coverts are darkish olive brown, 

 with very indistinct light shaft stripes, and the side of the 

 neck is the same colour as the upper parts but slightly lighter 

 and unspotted. The wing-feathers are the same colour as the 

 upper surface of the tail, broadly margined with the same 

 colour as the back, and slightly reddish at the root of the 

 outer primaries, forming an indistinct patch, but disappearing . 

 at the tip of the primaries and inner web of the secondaries. 

 The throat is whitish buff, crop region buffish olive yellow, 

 centre of breast and abdomen whitish, blending into whitish 

 buff on the long under tail-coverts, the latter being furnished 

 with a dark centre, which, however, does not reach to the tip 

 of the feathers. The under surface of the tail is brownish 

 grey, suffused with lavender grey. The sides of the breast 

 and body are of the same colour as the back, but rather 

 lighter and unspotted, though at the roots of the tail the 

 feathers have dark but not very conspicuous centres. 



Adult Male in Summer. — The upper parts are of an olive 

 greyish green, very slightly tinged with yellowish umber, each 

 feather having a dark brown centre, most conspicuous on the' 

 crown and back, but more indistinct on the nape and upper 

 tail-coverts. The upper part of the tail is uniform, the olive 

 umber being stronger, and the shafts a lavender brown. The 

 wings are a dark greyish brown, but the broad margins of olive 

 greyish green make the closed wing look almost uniform in 

 colour ; the first and second primary each have a whitish brown 

 edge. There is an indistinct whitish ochre superciliary stripe 

 disappearing behind the eye. The lores are greyish, sides of
