|Zoothera dauma major
This large, heavily patterned thrush is similar in appearance to the scaly thrush, to which it is usually considered a subspecies. It has warm olive-brown to buff upperparts and whitish underparts with heavy black scaling. It has twelve tail feathers. The scaly thrush is smaller and has fourteen tail feathers. It has a cheerful song similar to the Siberian thrush. Among thrushes, only the blue whistling thrush typically attains a larger size. The Amami thrush ranges in length from 29 to 31 cm (11 to 12 in) and weighs approximately 172 g (6.1 oz). Among standard measurements, the wing chord is 16.4 to 17.3 cm (6.5 to 6.8 in), the bill is 3.1 to 3.3 cm (1.2 to 1.3 in) and the tarsus is 4.1 to 4.5 cm (1.6 to 1.8 in).
This bird is critically endangered due to forest clearance. The current population is estimated at less than sixty. Areas of forest have been protected by the government primarily for the conservation of this species and the Lidth's jay.
The breeding population is estimated by Amami Ornithologists' Club (NPO, Japan) all over the island every late March since 1999. The total number of singing birds, which may be territory holders, counted were more than 162 in 2006.
Since 2006 this taxon is no longer recognised by BirdLife International. It has been lumped into Zoothera dauma following Collar (2004). As a subspecies its conservation status is no longer classified.
