initiating its breeding cycle* fen of 31 nests checked were empty and the rest 'contained 
eggs, nine of which were fresh, (notes) Scattered all over island in .little clusters, 
probably 7-8,000 mhiskn birds* Checked 21 nests with eggs; found 9 of the eggs to be 
clean, pinkish when candled (against sun) and the rest were dirty and opaque (well- 
incubated V) A large number of immatures 2-3,000 are present,many still on nests* 
Eo small young observed. Of 31 birds sitting on nests: 11 males on eggs 
10 females on egg 
4 males on empty nests 
6 females on empty nests* 
[Egg measurements for 21 eggs given in notes] . * .Opaque eggs were quite dirty and 
several were bloody.. Nests were scattered here and there mostly on low platforms 
constructed loosely of Solanum and Sida stems*
