Measurements.—Measurements are listed in [table 50].
Specimens examined.—Total number, 30 (15 males, 14 females, 1 unsexed), as follows: Palau Islands, USNM—Babelthuap, 2 (Nov. 27)—Koror, 4 (Nov. 14, 19)—Garakayo, 4 (Sept. 18, 19); AMNH—exact locality not given, 20 (Oct., Nov., Dec.).
Molt.—All birds examined (taken in September, October, and November) are in molting plumage.
Food habits.—At Garakayo, birds were observed in small flocks feeding in low trees. Two stomachs examined, which were from individuals of these flocks, contained very small seeds.
Remarks.—Oustalet (1895:207) first pointed out the relationship between the Bridled White-eye at Palau and the one at Rota. Hartert (1898:57) thought that the occurrence of the same kind of bird at Palau and at Rota was "very peculiar." It was not until 1931 that Takatsukasa and Yamashina separated the two populations by name.
Coultas (field notes) found the Bridled White-eye to be uncommon in the Palaus in 1931. He observed them in the tops of trees, noting that they were wary and easily frightened away by the shooting of a gun. Coultas writes that he found the birds to be numerous at Peleliu; in 1945, the NAMRU2 party did not find the birds at that island. The only locality where they were found to occur was on the small island of Garakayo where the writer shot four Bridled White-eyes on September 18 and 19. He found two or three small flocks in low trees near the summit of a hill on the island. Approximately 25 birds were in this area.
