In habits it does not differ from its allies. Its nest and eggs 

 are not known.

$ ad. (Siberia). Upper parts olive-green ; under parts yellowish 

 white ; a very indistinct coronal stripe, often absent, greenish grey ; 

 superciliary stripe greenish yellow, well defined ; wings with two distinct 

 bars ; axillaries and under wing-coverts yellow ; bill brown, yellowish white 

 at base of lower mandible ; legs brownish flesh ; iris brown. Culmen 0'45, 

 wing 2'1, tail 1'7, tarsus 0'7 inch ; 1st primary short but 0'25 longer than 

 the wing-coverts and 0'9 shorter than the 2nd which is intermediate 

 between 6th and 7th, 3rd and 4th equal and longest. In the autumn the 

 plumage is greener, and in the summer greyer. 



Hob. Siberia from the Ob to the sea of Ochotsk, and from the 

 Tschuktchi peninsula through Central Asia to the Himalayas, 

 wintering on the plains of India, Burma, and south China. On 

 passage it occurs west of the Ural, and has , been met with on 

 several occasions in Heligoland, Germany, Austria, and Great 

 Britain. 



Frequents groves, bush covered localities and gardens, and is 

 not often seen in the true forest. Its call-note resembles the 

 syllables tiss-yip and the song is a loud double chirp, which can 

 scarcely be called a song but which is continually uttered. The 

 nest is semi-domed, constructed of grass and moss and lined 

 with finer grass, and lined with hair, and is placed on the 

 ground or in a low bush close to the ground. The eggs 5 or 6 

 in number are white, with reddish brown surface-spots, and a 

 few purplish grey shell-markings, the spots being frequently 

 collected round the larger end. In size they measure about 

 0*6 by 0*45 inch. The Himalayan bird has been described as 

 distinct (P. humei Brooks) but after a careful examination of a 

 series I cannot endorse this view.
