 in considerable numbers with the Sterna Ilirundo, breeding on 

 those islands, the nests of both birds being intermingled. 



The male and female are nearly the same size, the latter is 

 rather the smallest, but their plumage is exactly similar. The 

 length of different specimens varies from twelve and a half to
