Nesting in widely scattered areas of grassy interior. Probably minimum 
of 1 , 000 eggs present but only one small chick found. 
(BBC sum) 3000 + Nesting in scattered colonies 
under Scaevola and at the base of grass clumps. Nests were not very 1 
densely situated possibly &ur to the roughness of the terrain casued by 
the many shearwater and petrel burrows. However, two nests were found 
but 8 inches apart on the opposite sides of a grass clump. Some 324 birds 
were banded from eggs. (Note under Peregrine Ealcoh for predation) 
(DBS Mar. 13) Sis Gray-backed Terns sitting on the 
Scaevola over a nesting colony. There are nesting colonies of Grey-backs 
all over the island. There was one area l/4 mile long with Grey-backed 
Terns nesting in the giragro_stis_ variabilis , there were thousands. 
(DBS summ) I would say there are at least 10, 000 
breeding birds with nests and a total population of 15 , 000 . ¥e found 
one small chick which could not have been over 3 days old.
