Description

It was general ashy grey with a white underbelly. Undertail coverts and the tips of the outer tail feathers where coloured white too. The bill, the feet, and the naked eye-ring were red. The wing length was 13,5 centimetres and the length of the tail was 11 centimetres. The bill reached a length of 2. 4 centimetres and the legs were about 3. 8 centimetres long.

Habitat

Its habitat was in the north and north-east of Grand Cayman. It consisted of swamps and mangroves with poisonous Manchineel trees (Hippomane mancinella) as well as of areas with knife-edged coral rocks and the climbing cactus (Epiphyllum hookeri). The Manchineel tree ( Hippomane mancinella) is a species of Flowering plant in the spurge family ( Euphorbiaceae) native to the Caribbean

Extinction

Charles B. Cory described them as common in 1886 but shortly after its discovery it became a favorite object for bird collectors. Charles Barney Cory ( January 31, 1857 - July 31, 1921) was an American Ornithologist and Golfer Cory was Twenty-one specimens were collected on four occasions in total. The first four specimens were taken in August 1886. Another three were killed in 1892 and one female was obtained in 1896. Finally thirteen specimens were shot between April and July 1916 by bird collector W. W. Brown, jr. . Suddenly this bird was vanished and several surveys to find this species again have failed until zoologist C. Bernard Lewis observed one indivual north of East End in the eastern of Grand Cayman in the summer of 1938. This was the last reliable report of a living Grand Cayman Thrush. Causes of its extinction were most likely deforestation and the destroying of its habitat by hurricanes between 1932 and 1944.
