Geographic Range [top]

Range Description: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 (Hindwood 1940). It could not be found in 1928 (Sharland 1929).
