The Izu Thrush (Turdus celaenops), also known as the Izu Islands Thrush, is a thrush native to the Izu and Ryukyu Islands of Japan, in particular, Hachijojima, Mikurajima, and Miyakejima in the former chain, and Yakushima and the Tokara Islands in the latter.
The clan’s fortunes went into eclipse when Ōoka Tadashina (1667–1710) so displeased Shogun Tokugawa Tsunayoshi that he was exiled to Hachijojima and Ōoka Tadafusa (1650–1696) was forced to commit seppuku for killing a retainer of the Shimazu clan in a brawl.
