Harbour except in very severe "weatlier. Immature birds, 

 as in tlie case of Larus cachhmans, vastly outnumber those 

 which are in full plumage. These Gulls are exceedingly 

 tame and confiding, coming right alongside a ship at 

 anchor,, so that they may be almost touched with a stick. 



Larus cachinnans. 



The Mediterranean Herring Gull is possibly the only 

 Herring Gull which visits the Kwang Tung coast in the 

 winter month's. The earliest date on which it was noticed 

 was September 27, and the latest April 24. 



Considerable numbers crowd into Hong Kong and Tolo 

 Harbours and into the Western Approaches and Deep Bay, 

 when the north-easterly gales occur in the winter and early 

 s^Jring; but of these the vast majority are immature birds. 

 Mature specimens of Larus cachinnans have often been 

 observed and several times obtained in Hong Kong and 

 Tolo Harbours, but no undoubtedly mature specimen of 

 Larus vegce was either seen, or shot. It seems doubtful, 

 however, whether the young of these nearly allied species 

 are distinguishable, and therefore it is quite possible that 

 both species of Herring Gulls are represented. 



Larus canus. 



The Common Gull is a moderately frequent winter visitor 

 to the Kwang Tung coast, but it does not leave the salt 

 water. 



Larus glaucus. 



An immature specimen of the Glaucous Gull was noticed 

 on several occasions in Hong Kong Harbour, during severe 

 weather with north-easterly winds, during February 1908. 



Nettopus coromandelianus. 



The Cotton Teal Goose is a species of somewhat irregular 

 occurrence, but has been noticed at all times of the year 

 both on the river and in the Delta. Usually on fresh water, 

 this species has been observed in other situations and on 

 the lotus ponds.
