Here's another image from "Songbird ReMix Magpies" (to be released very soon). This image features two different magpies; the Red-billed Blue-Magpie (left) and the Yellow-billed Blue-Magpie (right). Apart from the bill color (red-orange Vs yellow), the Yellow-billed can be easily identified by the white crescent of the nape of its neck. Both birds are from Asia and share the same habitat in Vietnam. The Red-billed Blue-magpie ranges from the western Himalayas eastwards into Myanmar, Thailand, Cambodia, Laos, and Vietnam, and through central and eastern China to southwest Manchuria. There was a small feral population, originating as escaped caged birds, became established for a while on Oahu, in Hawaiian Islands, but seems now to have been exterminated. It is omnivorous, but mainly carnivorous. Prey items include wide variety of larger invertebrates, especially beetles, caterpillars, land-leeches, tree-frogs, small lizards, birds' eggs and nestlings, and even small mammals. It will also take carrion and kitchen scraps. A variety of fruits and berries also taken. The Yellow-billed Blue-Magpie is endemic to northern parts of the Indian subcontinent, including the lower Himalayan foothills, with a disjunct population in Vietnam.
