The cardinal myzomela (Myzomela cardinalis) is a species of bird in the honeyeater family. It is named for the scarlet color of the male. It is found in American Samoa, New Caledonia, Samoa, Solomon Islands, and Vanuatu. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. It frequents areas with flowers, such as gardens. This is a small, active bird, measuring about 13 cm (5.1 in) from bill to tail. Males are red and black in coloration, females are grayish-olive, sometimes with a red cap or red head. Its long, curved bill is especially adapted for reaching into flowers for nectar. Cardinal myzomela populations have vanished from the island of Guam since the invasion of the brown tree snake.
