Introduced into France for their fur in the 19th century these are now an established part of the Provencale fauna. Ragondin in French and not popular with our fabulous host at Mas des Demoiselles due to their rather ratty looks (and French name), I reckon these are pretty cool and not difficult to see here at the Parc Ornithologique in the Carmargue. This family party of an adult with at least three young were feeding close to one of the paths and, although wary, would approach quite close. The adult was not very tolerant of the young when they approached though.
