MoTACILLA OCULARIS. 



The Streak-eyed Wagtail is an exceedingly common bird 

 of passage at Hong Kong, Macao, and on the Kwang Tung 

 coast generally. Although appearing as early as August 9 

 on migration, the latter part of September or early October 

 is the more usual time for their advent, when immense 

 numbers may be seen on the cricket-ground and in tiie 

 Naval dockyard and elsewhere on the island of Hong Kong. 



The birds on their passage usually roost in the trees, and 

 as many as fifty were observed to crowd themselves, with 

 much bickeriug, into a small tree in the Naval dockyard. 

 They leave again on the spring migration in April, and 

 probably only breed in the far north of Asia ; they do not 

 occur inland, so that their migration is along the coast-line. 



At Hong Kong this species is very much more numerous 

 than Motacilla leucopsis.
