Liverpool Pigeon Caloenas maculata



Justification

Justification of Red List Category
The one specimen of this poorly-known species may have come from Tahiti, French Polynesia, but it has not been reported there since 1928, when the only possible sightings of the species were made. It is presumed Extinct, and is likely to have been hunted.

Population justification
No population was ever discovered.

Distribution and population

Caloenas maculata is known only from one surviving specimen in the Merseyside County Museums, and one lost specimen, collected between 1783 and 1823. The providence of the specimens is unknown, but it seems most likely to have been a Pacific species, given the main area of activity of its collectors. Its short, rounded wings suggest it evolved on a small predator-free island. It was possibly the bird described by the people of Tahiti in 1928 as being speckled green and white (Gibbs 2001). It is likely to have been almost extinct before European exploration of the Pacific began.

Ecology

Nothing is known, although given its colouration it is likely to have been a forest dweller.

Threats

Although purely speculation, it is not unreasonable to assume that hunting for food and perhaps predation by human commensals were responsible for its extinction.
