Zee-wa-so, Burmese (generic). 



Coloration. Very similar to that of C. innomhuctn, but the size is 

 smaller and the tarsi are naked. The riimp-band varies in distinct- 

 ness, being ill-defined and brownish grey in Andaman birds 

 (C inexpectata), greyish white and well marked in those from 

 Tenasserim (C. merguiensis). The pale rump-feathers are always 

 dark-shafred, those of the lower surface sometimes. 



Bill black ; irides very dark brown ; legs and feet brown (Davison). 



Length 4*75 ; tail 2-1 ; wing 4*7 ; tarsus '4. 



Distrlhutinn. Islands of the Pacific and Indian Oceans from 

 Samoa to Mauritius, ranging and breeding throughout the Malay 

 Archipelago to the coasts of Burma (Tenasserim and Arrakan) 

 and the Andaman and Nicobar Islands. 



Habits, &'c. So far as is known, this bird, which produces the 

 best kind of the edible birds' nests of commerce, keeps mainly to 

 the sea-coast. The nests are entirely, as Hume has shown, com- 

 posed of inspissated saliva; they are white except where they are 

 fastened to the rock. The breeding-season in the islands of the 

 Bay of Bengal begins in March. Eggs measure 'SI by -53.
