The diet and mode of foraging described by Feuilley matches that of an ibis , whereas members of the Raphinae are known to have been fruit eaters . Accounts by early visitors indicate the species was found near their landing sites , but they was found only in remote places by 1667 . The bird may have survived in eastern lowlands until the 1670s . Though many late 17th century accounts state the bird was good food , Feuilley stated it tasted bad . This may be because it changed its diet when it moved to more rugged , higher terrain , to escape pigs that destroyed its nests ; since it had limited flight capabilities , it probably nested on the ground .
