A long-tailed bird of upper montane forest. The male has an iridescent green head and bib with a black chest band bordered with a thin gold stripe. Note the outlandishly long, white tail streamers. Female is blackish with barring on the belly and some iridescence on the head. Mainly eats fruit. Similar to Stephanie’s Astrapia, but Ribbon-tailed usually occurs at higher elevations. The female Ribbon-tailed has iridescence on the head and the male’s tail is white rather than black. Voice, excited, pulsing rasps.
