Ecology and description
The Ryukyu green pigeon was formerly considered one of the subspecies of the Taiwan green pigeon (Treron formosae), but recent molecular studies support its status as a separate species. Unlike the Taiwan green pigeon, this species has no red on its head.
The Ryukyu green pigeon has two subspecies:
- Nominate subspecies Treron permagnus permagnus: distributed from Yakushima to Okinawajima.
- Yaeyama subspecies Treron permagnus medioximus: found on Miyakojima, Ishigaki, Iriomote and Yonaguni.
The two subspecies look almost identical. The Yaeyama subspecies is slightly smaller, and in the field they are mainly distinguished by where they are found.

Field photographs taken during our tours, with observation dates
The chance of seeing the Ryukyu green pigeon (nominate subspecies) on Okinawajima is not high, though its calls are occasionally heard. The chances of seeing it on Amami Oshima are higher.
