taking note of as many pairs as possible pj,us noting the 
contents of the nests* Almost all of the nests on the 
outer perimeter cr the island were found so the totals 
obtained should probably represent a fairly accurate 
census of the total nests# _nests contained 1 egg* 
_2 eggs* _ 1 egg and 1 young_2 young* and 
a single small to rather large young# (There null probably 
be some overlap* as other individuals of the party caught 
and recorded boobies at times when 1 was not present and 
did not mark them) Almost all the nests were at the ddge 
of the vegetation either along the beach properor along 
areas of said projecting inward to the center of the island

IS 13 June 16-19*66 (PCS rept) "Nesting birds were restricted to the edge 
of Scaevola at the top of the storm beach, but were 
found here all around the island. No concentrations of 
nests occurred. Inland areas jwere apparently too well 
vegetated for tills species, E lg the nest count made 
18 June, 33 young, all singles, and three incubating 
eggs were found. Young ranged from freshly hatched to 
fully fledged, but most were a quarter to half grown. 
One large, recently dead young was seen on the east beach, 
with a parent bird still standing nearby.
