THE SUB-ALPINE WARBLER. SYLVIA SUB-ALPINA. 



Sylvia sub-alpina, Temm. Man. d'Orn. i. p. 214 (1820, ex 

 Bonelli, MSS.); Dresser, B. Eur. ii. p. 389, pi. 59 (1875). 



Adult Male. Slaty-grey above ; wings brown, with pale edges 

 to the coverts, the secondaries more broadly margined ; tail 

 brown, the three or four outside feathers with more or less 

 white ; chin, throat, and breast chestnut, shading off into paler 

 chestnut on the flanks ; the centre of the abdomen and under 

 tail-coverts whitish ; under wing-coverts pale grey, with darker 

 centres ; axillaries pale vinous grey ; a narrow white line along 

 the sides of the head separating the chestnut of the lower 

 surface from the grey of the upper ; bill dark horn-colour, the 

 lower mandible light yellowish at the base ; feet dusky brown ; 

 iris brown ; eyelid reddish. Total length, 4-6 inches ; oilmen, 

 0-45 ; wing, 2-3 ; tail, 2*1 ; tarsus, 07. 



Adult Female. Browner than the male above, and not so 

 ashy-grey. The chestnut of the under parts replaced by buffy- 

 white, with a vinous tinge on the sides of the breast. The 

 birds of the year are buffy-brown on the breast and flanks, the 

 male being a little greyer than the female. 



Characters. This little Warbler is allied to the Whitethroats, 

 but is smaller than any of them, the wing being less than 2-5 

 inches in length, while the colour of the legs and feet is brown. 

 It is distinguished from all the small Warblers of the White- 

 throat group by its chestnut chin and breast.
