Izu thrushes eat small animals, such as earthworms and insects, and fruits, like cherries or mullberries.

Their back and tails are black and they have a yellow eye-ring and bill, brown wings, and a rust-red chest.

Some less densely populated are on the Tokara Islands Yakushima, Kuchinoshima, Nakanoshima, Tairajima, Akusekijima and Takarajima.

In addition, there are wintering records from Shizuoka, Chiba, Mie and Wakayama Prefectures.

They are threatened by volcanoes, roads, railroads, wood plantations, tourism areas, and both native and invasive species and diseases.
