The Pied Wagtails are difficult birds to discnminate unless seen under 

 favourable conditions. The colour of the back and ear coverts are the 

 most important characters to note. The above records are somewhat meagre 

 in consequence of these contensions. 



222. Motadlla boarula melanope Pall. [832]. — The Grey Wagtail. 



Motadlla melanope. Gates, F. B. I., Vol. ii., p. 293. 



Cold season migrant at its first descent to the base of the foot hills in 

 North Lakhimpur is to be seen in the vicinity of habitations when it is 

 remarkably tame and not easily disturbed. It remains in these haunts for 

 only a brief period and forsakes these unusual quarters for its accustomed 

 haunts along the stony beds of the hill streams and rivers. It is then 

 very shy and difficult of approach.

 9-9-11*, single bird and at Dejoo on 17-9-07,$, 17-9-10*, single
