Tiny (bumblebee-sized) hummingbird of humid forest in the mountains of Mexico. Favors shrubby clearings and edges in evergreen forest and banks of flowers where other hummingbirds gather. Feeds while hovering in a horizontal position with tail cocked. Very inconspicuous, but male sometimes sings persistently from an exposed perch. Male has expansive, magenta-pink gorget, rather short tail with white corners and rusty base. Female has dark-spotted throat and same tail pattern as male. Very similar Wine-throated Hummingbird does not overlap in range.
