1922.] Bb'ds of Jhang District. '203 



I have also found a few in a small reed-bordercd jheel at 

 Pal)barwala. It is prosuinably a winter visitor only, but I 

 saw two at Massan as late as 26 March, 1919. The ordinary 

 call-note is a sharp " chuck," similar to the noise made in 

 cocking a gun ; the pleasing song is to be heard early in 

 February. 



Acrocephalus stentoreus brunnescens (Jerd.). (-t skins.) 



Observed on the spring migrations as follows : — 



1918 : one on 9 May and one on 14 May. 

 1919 : two on 6 May and one on 28 May. 



All the birds were found in the thick overgrown hedges 

 of my compound, and four of them Avere procured. A bird 

 seen at Chnnd on 19 August, 1919, was almost certainly 

 of this species. 



Acrocephalus dumetorum Blyth. (5 skins.) 



Bly til's Reed- Warbler passed through Jhang in some 

 numbers on the spring passages of 1918 and 1919. In 1918 

 it was first noticed on 7 April and continued common until 

 the middle of May, being last seen on the 16tli. In 1919 it 

 was first heard on 11 April and continued fairlj- common 

 until 23 May ; a single bird was seen as late as 7 June. 

 These spring migrants sing freely in the hedges. On the 

 autumn passage it was only observed in 1919, when a few 

 birds passed through in August. 



Hypolais rama (Sykes). (5 skins.) 



Hypolais caligata (Licht.). (8 skins.) 



Both these small Tree- Warblers occur in the district in 

 some numbers on the spring and autumn passages. They are 

 very difficult to distinguish in the field, so I was not able to 

 make any accurate notes as regards the dates of either species 

 separately. But although they do not appear to mingle with 

 each other, each species being in patches, so far as I could 

 ascertain, both probably arrive and disappear about the 

 same time. At any rate, on the spring passage Tree-Warblers 

 arrive occasionally as early as the end of Marcb, but more
