area from the lighthouse north to the "guano hill” contained 28 percent of 
the nests. Most of the remaining 21 percent of the nests were located just 
north of the "guano hill" or on the east side of the island opposite the 
central lagoon.

has been recapture"! on other islands in the Line and Phoenix groups and 
birds from these islands have been recaptured on Enderbury. (see introduc¬

is that Blue-faced Boobies travel between Enderbury and all the islands 
with Blue-faced Booby colonies in our area of interest.
