Geographic range.—Micronesia: Caroline Islands—Ponapé.

Characters.—Adult male: Resembles adult males of M. c. rubratra, but with more extensive black markings on lores and below eye; tips of feathers lighter "scarlet."

Adult female: Resembles adult female of M. c. rubratra, but duller and with red coloring much reduced; head, neck, shoulder, ear-coverts, and sides of neck sooty brownish-gray; rest of upper parts dark brownish-gray with plumage of middle of back, rump, and upper tail-coverts tipped with scarlet; wings and tail dark brown with outer edges olivaceous-gray; chin and throat reddish; breast light brownish-gray, may be washed with reddish; axillaries, abdomen, and under tail-coverts grayish.

Immature male: Resembles adult male, but scarlet coloring less brilliant and thinner on forehead, middle of back, rump, upper tail-coverts, and underparts and absent, or nearly absent, on crown and neck.

Immature female: Resembles adult female, but scarlet coloring thinner and present only on underparts, back, rump, and upper tail-coverts; abdomen and under tail-coverts washed with buff.

Measurements.—Measurements are listed in [table 48].

Specimens examined.—Total number, 52 (26 males, 24 females, 2 unsexed), as follows: Caroline Islands, USNM—Ponapé, 3 (Feb. 11, 12); AMNH—Ponapé, 49 (Nov., Dec.).

Nesting.—Yamashina (1932a:395) records a large collection of eggs of the honey-eater, taken at Ponapé in 1931. Of 13 sets of eggs listed, 10 include two eggs per set and 3 include one egg per set. These were obtained from July 20 to September 2. Coultas (field notes) found one nest with young in a tree-fern in the period of November and December, 1930. The nest was cup-shaped and made of fern and fine grasses and lined with lichens. Coultas writes that only the female feeds the young. He suspects that the honey-eater nests at all times of the year.

Molt.—Most of the birds taken by Coultas in November and December are in molting plumage.

Remarks.—The Cardinal Honey-eater at Ponapé is, according to Coultas, found in most habitats of the island. He found it to be an aggressive bird, often chasing the white-eye Zosterops cinerea. The committee (Hachisuka et al.) which prepared the Hand-list of Japanese Birds in both the revised edition (1932) and the third edition (1942) does not recognize the Ponapé honey-eater as separable from the bird at Kusaie. I see no reason for this action and find the bird at Ponapé to be a well-marked subspecies.
