Distribution. — The Damara Tern is found along the south-west 

 coasts of Africa from Loango to Table Bay ; it was first obtained by 

 Andersson at Walvisch Bay, where it breeds ; Layard and sub- 

 sequent collectors have met with it on Sobben Island off Table 

 Bay in the months of March and November, in the former case 

 in non-breeding, in the latter in breeding plumage. It has not 

 been deBnitely recorded from the southern coasts of the Colony, 

 or from elsewhere along the South African coast-line. 



Habits. — Andersson states that at Walvisch Bay, where it is 

 very abundant, this little Tern flies in pairs or small flocks, uttering 

 harsh and rapid cries. It feeds on small fishes and crustacea, in 

 search of which it explores the creeks and shallows left by the 

 receding tide. It is swift of flight and rapid of movement. Anders- 

 son found this bird breeding at Walvisch Bay, the eggs being 

 deposited in a small hole scooped in the sand.
