A sluggish bird of mature tropical hill forests. A small head and prominent pale eye-ring give it a comically surprised appearance. Male has a wine-purple back, a scarlet belly, and a red plush patch on the forehead. Female is brownish with a yellow cap and underparts. Like other trogons, usually still and hard to detect on a low or mid-level perch, from which it sallies out to take insects, fruits, and seeds. Song is a series of bubbling hoots that accelerate and rise, then taper off gradually towards the end.
