82 THE BIRDS OF RAINHAM. 



SANDWICH TERN. 

 Sterna cantiaca, Qmel. 



The Sandwich Tern is but seldom seen on the 

 Medway. It comes in the autumn when a few 

 immature specimens have been shot. 



COMMON TERN. 

 Sterna fluviatilis, Naum. 



This is the Common Tern or Sea Swallow of the 

 Medway ; provided the season is favourable they 

 sport on the calm water in the autumn for a fortnight 

 at least, their graceful pitching and rapid flight is 

 always pleasing to see. 



ARCTIC TERN. 

 Sterna macrura, Naum. 



I have never been able to recognise the Arctic 

 Tern among the many common Terns that some- 

 times visit our river ; in the autumn possibly they may 

 have occurred, but have not to my knowledge been 

 shot. 



LESSER TERN. 

 Sterna minuta, Linn. 

 The Lesser Tern is not uncommon on the Medway.
