Which owl has flame-colored feathers that give it its name?

The Flammulated Owl (Otus flammeolus) has flame coloured feathers which give the owl its name. It gained its scientific name of flammeolus from the Latin Word for 'flame' or 'flame-shaped', a direct reference to its flamelike colouration.
