Large and spectacular hummingbird found in the Andes of southern Ecuador and northern Peru. Plumage varies geographically, but all birds have bright chestnut on lower back, tail, belly, and wings, along with a green breast. Crown color ranges from rusty at the northern limit of its range to glittering green and blue farther south. Throat patch may be purple or blue and varies in size. Also note rather long bill. Female is duller than male and lacks throat patch and iridescence. Inhabits montane forest and scrub, and occasionally visits feeders.
