Large, spectacular, and solidly built hummingbird of humid evergreen and pine-evergreen forest in mountains; uncommon. Feeds at all levels on flowers and sometimes perches on prominent high twigs. Most striking feature is the bright rusty wings, which typically flash brightly as it hovers at flowers; also note the big white spot behind the eye. Male often looks blackish below; the pink throat rarely catches the light. Female is dusky grayish below.
