Mascarene Coot
Encyclopedia
The Mascarene Coot is an extinct species of coot
that inhabited the Mascarene islands of Mauritius
and Réunion
. Long known from subfossil
bones found on the former island, but only assumed from descriptions to also have been present on the latter, remains have more recently been found on Réunion also. Early travellers' reports from Mauritius were, in reverse, generally assumed to refer to Common Moorhen
s, but it seems that this species only colonized the island after the extinction of the endemic coot. The Mascarene Coot was a large bird and while not flightless, it had reduced flying ability, so that if pursued, it would have even more preferred to escape by diving than it is already a general habit of the coots. As the bird had considerable stamina, it could have easily crossed the ocean between the islands, explaining why a single species occurred on both islands. The birds looked like oversized Eurasian Coot

The species fared little better on Mauritius, with Leguat (1708) being, in 1693, the last to record the endemic poules d'eau, saying they were "already rare". Apart from hunting, settlement activity leading to destruction of the marshland habitat seems to have played a major role in the species' extinction.
