BIRDS OF BRITISH BURMAH. 
This beautiful Tern appears to frequent only the sea-coasts and not to 
come inland. It breeds on isolated rocks and sand-banks. Mr. Parker 
found a colony nesting in June on a low bank on Adam's Bridge, Ceylon ; 
each nest^ a mere depression in the sand, contained one or two eggs, and 
their colour appears from his description to have been of the usual type, 
buff blotched with brown.

The Allied Tern is said by Mr. Blyth to be found on the coasts of 
Arrakan and Tenasserim. In this case it must also be found on the coast 
of Pegu. No recent observer in Burmah has met with it. 
It occurs in the Mediterranean sea, ranging down the eastern coast 
of Africa and along the whole southern coast of Asia through the 
archipelago to Australia. 
This Tern frequents the sea-coast and is likely to be met with in 
Burmah at all seasons of the year. Its breeding-haunts in Indian waters 
have not yet been discovered.
