 Leguat mentioned that pigeons only bred on islets off Rodrigues, due to predation from rats on the mainland. This may be the reason why Tafforet only observed the Rodrigues starling on an islet. By Tafforet's visit in 1726, the bird must have either been absent or very rare on mainland Rodrigues. Rats could have arrived in 1601, when a Dutch fleet surveyed Rodrigues. The islets would have been the last refuge for the bird, until the rats colonised them, too. The Rodrigues starling was extinct by the time French scientist Alexandre Guy Pingré visited Rodrigues during the French 1761 Transit of Venus expedition.
