ICTERINE WARBLER. . l8l 



Most of the recorded visits of this bird have been in Sep- 

 tember or August, and until more evidence of nesting is forth- 

 coming it must be looked upon as an occasional autumnal bird 

 of passage, which may be distinguished from the Sedge-Warbler 

 by the central buff streak on its crown, its buffer eye-stripe, 

 pale cheeks, striated rump and stronger striations on its back. 

 Length, 4*9 ins. Wing, 2*4 ins. Tarsus, '8 in. 



Radde's Bush-Warbler. Lusci7iwla sckwarzi (Radde). 



A single example of this eastern Siberian bird was shot by 

 Mr. Caton Haigh in Lincolnshire in 1898 ; as its winter quarters 

 are in southern China and Burmah, it can only be looked upon 

 as a lost wanderer. It is a small olive-backed warbler, with a 

 buff eye-stripe which bends round the cheeks to the nape. 

 Length, 5 ins. Wing, 2*45 ins. Tarsus, '9 in. 



Moustached Warbler. Luscmiola viekmopogon 

 (Temm.). 



The Moustached Warbler is a south European and north 

 African bird which was added to the British list in 191 5, on the 

 strength of an example which had wandered to Sussex. Mr. 

 Witherby states that it can be distinguished from the Sedge- 

 Warbler, which it superficially resembles, by a blacker crown, 

 more chestnut upper parts, whiter eye-stripe, more rufous under 

 parts, larger first primary, rounder wing and more graduated 

 tail. Length, 5*25 ins. Wing, 2*2 ins. Tarsus, 7 in. 



Icterine Warbler. Hypolais icterina (Vieillot.). 



The Icterine Warbler (Plate 76) is now looked upon as a 

 rare but more or less regular bird of passage, occurring both in 

 spring and autumn in various parts of the British Isles, though
