purple-tailed imperial-pigeon Ducula rufigaster

A fairly large pigeon of lowland and foothill rainforest interior. Pale pinkish head, orange underparts, metallic emerald green wings and back, and a purple rump. It is usually solitary, difficult to see and does not usually fly above the canopy. Similar to Rufescent Imperial Pigeon, but Purple-tailed is found at lower elevations and has an obvious pale gray tail band. Call, two introductory “tuk-tuk” notes followed by a long, rather out of tune, rising then falling “ooo-woo-ooo”
