_Geographic range._--Indian Ocean east to central Pacific islands.
In Micronesia: Mariana Islands--Maug, Medinilla, Saipan, Rota;
Palau Islands--exact locality unknown; Caroline Islands--Lukunor;
Marshall Islands--Bikar, Likieb, Bikini, Eniwetok.
_Characters._--Adult: A large sea bird with plumage of variable
color, mainly white or partly buff with black primaries and
black-tipped secondaries, or grayish or brownish with white or
grayish tail; throat blackish; face blue or green; bill bluish and
lighter at tip; legs and feet red.
Immature: Resembles adult, but often wholly brownish, lighter
ventrally; bill blackish; feet yellowish red. Immature resembles
that of _S. leucogaster_.
_Nesting._--Morrison obtained a male nestling at Bikini on May 3,
1946.
_Specimens examined._--Total number, 10 (3 males, 7 females) from
Marshall Islands, USNM--Bikini (April 28, May 1, 2, 3).
_Remarks._--The writer saw several birds approximately 20 miles east of
Eniwetok on January 7, 1945. Morrison obtained a series of birds at
Bikini in April and May, 1946. Murphy (1936:861-870) presents a wealth
of information concerning the bird. He points out the need for a better
understanding of the plumages of the adult birds and gives evidence that
the birds of different colors may occur within the same population. He
describes the Red-footed Booby as nesting in trees and shrubs. This type
of nesting environment is present at many of the islands in Micronesia.
