Rusty-backed Thrush

The red-backed thrush or rusty-backed thrush (Geokichla erythronota) belongs to bird in the family Turdidae. Traditionally, it included the red-and-black thrush (Z. mendeni) as a subspecies. Its natural range is restricted to forests on Sulawesi and the nearby islands of Buton and Kabaena in Indonesia. Geokichla erythronota is very similar in morphology to the chestnut-backed thrush (Geokichla dohertyi) and some authorities believe they are conspecific. (Wikipedia, general species account).

The red-backed thrush is about 20 cm (8 in) long and the sexes are largely similar in appearance. It is becoming rare due to habitat destruction. A subspecies (G. e. kabaena) has been named from Kabaena and some researchers believe there is an unnamed race of G. erythronota on the island of Buton, the status of which needs to be evaluated.
