320 TRAVELS OF A NATURALIST 



shot, attracted to within range by my imitation of a 

 mouse's ' cheep.' He was skimming low over the tops 

 of the trees. 



One Blue-headed Wagtail was got, and one Ked- 

 throated Pipit, and three more of the perching Pipits, 

 which we will for the present call A. arborensis (/). 

 Measuring them, we find them again agree with those 

 already noted, but a male is slightly larger than a female. 

 M. Znaminsky and I each shot a Golden Plover out of a 

 small party of seven or eight. 



We went again to the same wood to try principally for 

 Pipits, and bagged some Willow AVarblers, a ? Blue- 

 headed Wagtail, a Blue-throat, etc. 



At another place, a deepish valley with much the same 

 kind of wood growing in it, shot two J AVheatears and 

 another Siberian Chift'chaff, and had the satisfaction 

 of hearing its voice and song well beforehand. It began 

 with a 'chiff-chaff-chaff' and then stopped suddenly, the 

 first time we heard it, and the second time it rapidly 

 repeated the same syllables, running them into an actual 

 song. Neither in this specimen is there any appearance 

 of yellow on the neck, and we begin to think our descrip- 



faint tinge of ruddy ou the pale supercilia, sides of neck, breast, and 

 tlanks, axillaries, and fore part of the wing underneath, pure Ught 

 yellow.
