Zoothera terrestris
The Bonin Thrush, *Zoothera terrestris*, was a small, ground-dwelling songbird endemic to Chichijima in the Bonin Islands (Ogasawara Archipelago) of Japan, tragically driven to extinction shortly after its discovery. This stocky thrush measured approximately 23 cm (9 inches) in total length. Its plumage featured a distinct olive-brown upperpart, transitioning to sooty dark brown on the head and upper breast. The underparts were a contrasting pale grayish or whitish, marked with subtle brown m...
This thrush inhabited the dense undergrowth and thickets of subtropical forests on Chichijima, often observed foraging on the forest floor. It was likely found at low elevations near the coast where human settlement quickly encroached.
The Bonin Thrush's diet likely consisted primarily of ground-dwelling invertebrates, including insects, larvae, snails, and worms, which it would have found by foraging in the leaf litter.
Observations of the Bonin Thrush were exceedingly brief, offering only glimpses into its natural behavior. It was primarily described as a terrestrial bird, spending most of its time foraging on the forest floor, likely sifting through leaf litter for invertebrates, a common trait among *Zoothera...
The Bonin Thrush was strictly endemic to the isolated oceanic island of Chichijima, the largest island in the Bonin Islands (Ogasawara Archipelago), approximately 1,000 km south of mainland Japan. Its entire known range was confined to this single island. There is no historical evidence of its pr...
Extinct
- The Bonin Thrush holds the unfortunate distinction of being one of the most rapidly extinguished bird species known, disappearing within years of its scientific discovery. - Only four specimens of the Bonin Thrush are known to exist in museums worldwide, making it an exceptionally rare and valu...
