Population justification
No extant population remains.
Zosterops strenuus was endemic to lowland forests on Lord Howe Island, Australia (Stattersfield et al. 1998). It was very common before 1918 (McAllan et al. 2004), with the last records coming from 1908 (Hull 1909), but it plummeted to extinction following the arrival of Black Rats Rattus rattus on the island in 1918 (Hindwood 1940, Hume 2017). It could not be found in 1928 (Sharland 1929).
It inhabited lowland forest, palm glades and the scrubby vegetation of more open and settled areas. It probably fed on fruit, insects, flowers and other birds' eggs (Garnett et al. 2011).
The cause of its extinction was predation by Black Rats.
