ハリオアオバト Treron apicauda

Like other green pigeons, usually seen flying overhead or perched in a fruiting tree. Green overall with a neon-blue bill and bright red feet. Sexes are similar, but males have a faint orange wash on the chest that females lack. Very long, sharp-tipped tail is diagnostic and evident both when in flight and when perched. Usually seen in pairs or small to medium-sized flocks in hill forest. Generally quiet; occasionally gives a high fluty “doo!” followed by two to three deeper coos.
