In November> 1963 there -were 34 nests with eggs but very few if any 
of these produced young. The interval between the November and February 
visits would not be sufficient for a young bird to hatch and fledge and the 
number of young birds seen in February would represent the maximum survival 
of young hatched from nests found in November. Apparently nesting in other 
periods was more successful since the number of nests with eggs found on any 
one visit is quite similar to the number of young found on succeeding visits 
(see Appendix A). _ .Qv'av'Ao e» ( ~^L~xc)Rl<.Qlcx^\ (^ w^vs<m YHOpST

Banding : Through M&sy 1965 a POBSP personnel had banded 179 adults, one sub- 
adult, 28 immatures and 3 6 nestlings. Two birds banded as adults were recap¬ 
tured on Howland Island and one bird banded as a nestling was recaptured on 
Funafuti in the Ellice Islands a year later. Two young birds (one from How¬ 
land and one from Birnie) and one adult from Phoenix were recaptured on

Prior Records : Cassin ( 1858 ) record^ that the Wilkes Expedition found Red¬ 
footed Boobies nesting on bushes in January, l84l. The nests were built of 
sticks and some contained fresh eggs while others were occupied by young birds 
in all stages of growth. He stated that two young or two eggs were rarely 
found in the same nest.
