On the whole the Ped-tailed Tropicbird nesting population shows relatively 
little change from its status on the July visit. Fewer nests were found 
but this may be due in part to an unexpected rate of mortality at the 
egg and small chick stage. 
Thirty-three nests were marked during the July visit with plastic, 
pressure sensitive tape in order that changes in nesting status over 
a month period might be determined. During the August visit a large 
part of two mornings was suent searching for these marked nests , 
Of the fifteen nests with eggs present and marked in July,4 or about
