74 RADDES BUSH-WARBLER. 



is common throughout South-eastern Siberia and in J)auria, and is 

 widely distributed in autumn ; but it is rarer in Ussuria, though it 

 appears to nest there, for it sings all through the summer. In the 

 early part of August, during our journey across the Government of 

 Yeniseisk, on the road between Irkutsk and Tomsk, it was also 

 singing, so that it probably nests there. On passage it frequents the 

 bushy margins of the forests, and it arrives early in June. Its song 

 is short and not very agreeable, but loud, and the alarm-note maj- 

 be rendered as gibout-gibout. We did not find its nest. It leaves 

 Ussuria about the middle of September. 



In winter Radde's Bush-Warbler visits Southern China, Pegu, and 

 the northern and central portions of Tenasserim (Oates, Fauna 

 Brit. India, i. pp. 399-400). Its large bastard-primary indicates its 

 connection with the genus Lnsciniola, in which Seebohm placed it ; 

 but Mr. Oates finds this genus too comprehensive, and relegates 

 the bird to Herbivoaila of Swinhoe. The upper plumage is 

 olive-brown, tinged with tawny, especially on the rump ; wings and 

 tail brown, edged on the outer webs with the colour of the back ; 

 supercilium very distinct and reaching to the nape ; lores and 

 feathers behind the eye dark brown ; ear-coverts buff and brown ; 

 lower plumage rich tawny-buff, paling on the throat and abdomen ; 

 axillaries and under wing-coverts buff. In summer the lower parts 

 are nearly white, merely tinged with yellow or buff, more especially so 

 on the vent and under tail-coverts. Bill horn-colour, the base fleshy- 

 white and the gape yellow ; iris brown ; legs and feet fleshy-yellow. 

 I.ength about 5-6 inches, wing 2 '45, tarsus 0-9 inch, bill from gape 

 0-65. The 2nd primary is equal to the Sth, or intermediate between 

 the 7th and Sth ; the ist (or bastard) primary is very long, measur- 

 ing 0-85 inch in length (Oates). 



The young bird, like Mr. Haigh's specimen, from which the 

 figure is taken, is decidedly more olivaceous on the upper-parts. 

 The bill is stout and deep for that of a Warbler, and the three rictal 

 bristles on each side are very strong, but the supplementary hairs do 

 not extend up the culmen nor cover the nostrils as in Phylloscopus. 

 (From 'The Ibis,' 1899, pp. 1-3.) The broad and abrupt 

 termination of the white superciliary stripe is very characteristic of 

 this species.
