house north to the guano heap and in one or two areas on the east side 
opposite the frigate colony. 
These ground nests were all in areas which afford protection from the 
wind. On some days during our visits there has been no wind movement at 
I 
these areas. Despite several reports to the contrary birds in these colonies 
show little difficulty in achieving flight without wind. Even birds en¬ 
tangled in vegetation have been observed rising in flight after some ener¬ 
getic flapping. 
Banding: Through June 1965 POBSP personnel had banded 734 adults, five 
immatures and l8l0 nestlings. A nestling banded November l8, 1963 fws found 
on Arorae Island, Gilbert and Ellice Islands on October 8, 1964. Another, 
* 
banded November 11, 1964, was found on Yap in the Caroline Islands on May 4, 
1965. One adult female banded July l4, 1963 was found nesting on Howland 
Island on May 19, 1965* .Clfel — 
Lesser Frigatebird (Fregata ariel) 
I964 and 1965. 
Prior Records : One specimen was collected on May 15/ 1939 by L. P, Schultz. 
Fopulation : The number of Lesser Frigatebirds on Enderbury have varied 
widely during the seven visits to that island made by the POBSP. The 
population has varied from 15/000 in July I963 and 1964 to less than 100 
adults in February 1964 and 1965. There were at least 10/000 breeding 
birds present in July of 1963 and 1964.

shows the decline in numbers from the summer peak.
