The Micronesian Myzomela is a red-and-black nectar-feeding bird that moves as flowers come into bloom. In the Mariana subspecies, the Guam population was gone by 1986; populations remain on Rota, Saipan, and Tinian.
Males are scarlet and black, while females are duller red and brown. The species shows clear sexual color differences.
It feeds mainly on nectar and uses habitats with nectar-bearing flowers. It defends all-purpose territories but also moves opportunistically as nectar becomes available; breeding may occur year-round.
An extinction-risk assessment has not been added yet.
