74* RADDE’S BUSH-WARBLER. 
is common throughout South-eastern Siberia and in Daiiria, 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 may 
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 Lwsciniola, in which Seebohm placed it ; 
but Mr. Oates finds this genus too comprehensive, and relegates 
the bird to Herbivocula 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. 
Length about 5-6 inches, wing 2°45, tarsus o’g inch, bill from gape 
0°65. The 2nd primary is equal to the 8th, or intermediate between 
the 7th and 8th; the 1st (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 Phyl/oscopus. 
(From ‘The Ibis,’ 1899, pp. 1-3.) The broad and abrupt 
termination of the white superciliary stripe is very characteristic of 
this species.
