Marianne White-eye

It reached a size of 10 cm (3.9 in), the wing length was 5.8 to 6.3 cm (2.3 to 2.5 in), the length of the tail was 3.8 cm (1.5 in) and the length of the culmen 1.1 to 1.2 cm (0.43 to 0.47 in). It was generally greenish yellow with chestnut-coloured flanks and a conspicuous white eye-ring. The forehead and a line above the eyes were yellow. The top of the head and the back were yellow olive. The wings and the tail were black and the underparts were pale yellow. It was similar in appearance to the Mayotte race of the Malagasy white-eye (Zosterops maderaspatanus mayottensis). Nothing is known of its ecology.

It is known with certainty only from the small granitic islet of Marianne Island 0.962 mi2 (2.49 km2) in the Seychelles about 6 km (3.7 mi) east of La Digue. Reports that it also occurred on Praslin, La Digue, Silhouette Island and Mahé are unconfirmed. Due to the habitat destruction through agricultural development it apparently became extinct between 1870 and 1900 (according to IUCN around 1888). An expedition in 1940 led by Irish zoologist Desmond Vesey-Fitzgerald failed to find it. There is one specimen in the Natural History Museum in London.
