 while the Bridled Tern was nearly if not (luite as wild as our 

 Common Tern though all three species, so far as man is 

 concerned, are subjected to exactly tlie same conditions. 



The Sooty Terns were more numerous than the Noddies. 

 They invariably laid on the ground, generally under the 

 bushes, making no attempt at nest-building other than a 

 slight hollow in the earth when circumstances permitted. 

 The Sooties were more common at the northern. Noddies at 

 the southern end of the key, where, however, both species 

 nested under the bushes more or less closely associated.
