Mountain Imperial Pigeon
Ducula badia
The mountain imperial pigeon is the largest pigeon species in its range at 43–51 cm (17–20 in) long. It has a fairly long tail, broad, rounded wings and slow wing-beats. The head, neck and underparts are vinous-grey with a contrasting white throat and brownish-maroon upperparts and wings, though the upper part of the body can be duller. The underwing is slate-grey and the tail is blackish with a grey horizontal line. The combination the maroon back with the large size give this species a distinctive appearance. Its call consists of a deep, resonant boom that is only detectable at close range.
