You will definitely see or hear owls, buzzards, woodpeckers and many common garden species, such as blue tits, great tits, blackbirds and robins. As well as woodland species including wrens, woodcock, wood pigeons and jays. The dawn and evening chorus in spring is truly euphonious.
We have seen, and previous guests have photographed, many species of butterfly found in Brittany; including the rare and impressive Old World Swallowtail and the uncommon Silver-washed Fritillary. Good website for butterfly identification: Butterfly Conservation
