 together. They leave again in March. 



Hydrociielidon leucoftera. 



White-winged Black Terns are seen every spring in small 

 parties, on their northern journey, but have not been 

 observed on their return to the south. Usually they are 

 noticed during the second week in May, but on one 

 occasion as late as June 2. They have been seen in 

 company with Sterna caspia and Sterna sinensis. Tliey

 particularly in the month of May, Avhen a steady stream of 

 small parties goes by ; but they are to be seen as early as 

 the end of January. They are observed fishing and feeding 

 on the flooded paddy-fields, but do not appear to go far 

 inland.

The Crested Tern has been observed twice on the coast of 

 Kwang Tung in the month of September; on one occasion 

 this was after a typhoon, which may have impeded or altered
