MONTICOLA SOLITARIUS. 



The Red-breasted Blue Rock-Tlirusli is a common winter 

 visitor to Hong Kong and the Kwang Tung coast generally, 

 and goes inland to the borders of Kwang Si. 



The numbers of this species vary considerably in different 

 years, sometimes a great many remain all through the 

 winter months, and in other years all seem to pass rapidly 

 through. At first these birds shew a tendency to hang about 

 the seashore, but they soon betake themselves to woods and 

 gardens and are not shy. 



From about the middle of October and until the middle 

 of November there is a considerable influx of these birds, 

 and they were seen as late as May 14th at Hong Kong. 

 It has been stated that this species sometimes breeds near 

 Macao and at the Marble Rocks, Samshui, but no eggs were 

 taken by the writers. 



MONTICOLA CYANUS. 



The Blue Rock-Thrush is perhaps rather more common 

 than the red-breasted form, and most that applies to the 

 one does so to the other, but it does not occur inland. 

 There is no doubt that in some years birds with blue breasts 

 are more common than birds with red, and also that the 

 former tend to arrive at different times from the latter ; but, 

 on the other hand, it also happens that birds of all grades 

 of red and blue colouring may occur in the same rush of 

 migrants. 



This bird is as tame as the other Rock-Thrush, and may 

 often be seen perched on houses and railings, shewing rather 

 a partiality for the vicinity of human beings. 



RUTICILLA AUROKEA. 



The Daurian Redstart is a common winter visitor to the 

 Kwang Tung coast, but its numbers vary considerably in 

 different years. The earliest date in the autumn on which 

 this bird was seen was October 30th and the latest in the 

 spring March 24th. 



This bird has the habit of shivering its tail from side to
