Grand Cayman Thrush

Turdus ravidus

The Grand Cayman thrush, known scientifically as Turdus ravidus, was a bird of ashy grey plumage, with a contrasting white underbelly. The undertail coverts and tips of the outer tail feathers also bore this white hue. Around the eye, as well as on the bill and feet, the exposed skin was a striking red. The bird's wing spanned 13.5 centimeters, while its tail measured 11 centimeters. The bill was 2.4 centimeters in length, and the legs stood at approximately 3.8 centimeters.


This thrush favored the northern and northeastern swamps and mangroves of Grand Cayman, where the toxic manchineel trees (Hippomane mancinella) grew. It also inhabited areas strewn with sharp coral rocks and the climbing cactus (Epiphyllum hookeri).


Endemic to Grand Cayman in the Caribbean, the Grand Cayman thrush was a bird that once flitted through its specific island home.


The Grand Cayman thrush was described as common in its initial discovery in 1886. However, it soon became a target for bird collectors, which led to its decline.


After being commonly sighted in 1886, the Grand Cayman thrush faced intense pressure from collectors, with a total of twenty-one specimens taken on four separate occasions. The last reliable sighting of this bird was in the summer of 1938. Deforestation and habitat destruction, particularly from hurricanes between 1932 and 1944, are believed to have been the primary causes of its extinction. The Grand Cayman thrush was declared extinct in the 1940s.

I love using the bird app, I have a pretty good knowledge of birds. But I do have some gaps in it, so it’s nice to have a safe space to check on a sighting to confirm the species. It’s really enjoyable and I love the badges you can collect. It’s like a real life Pokémon go.
