 A <unk> French Huguenot , François Leguat , used the name " solitaire " for the <unk> bird he encountered on the nearby island of Rodrigues in the <unk> , but it is thought he borrowed the name from a 1689 tract by Marquis Henri <unk> which mentioned the Réunion species . <unk> himself had probably based his own description on an earlier one . No specimens of the solitaire were ever preserved . The two individuals <unk> attempted to send to the royal menagerie in France did not survive in captivity . <unk> claimed that Bertrand @-@ François Mahé de La <unk> sent a " solitaire " to France from Réunion around 1740 . Since the Réunion ibis is believed to have gone extinct by this date , the bird may actually have been a Rodrigues solitaire .
