Northern Long-eared Owl - Asio otus
Otus in latin and ôtos in Greek refer to a night bird with ears, hence its English name "Long-eared". We should point out that in French there are two words for owl ‘la chouette’ and ‘le hibou’, the difference being in the tufts of feathers on its head which can be confused with ears. They are particularly noticeable on the Northern Long-eared Owl, but can lie completely flat when it is resting or in flight. Although solitary birds, Northern Long-eared Owls gather together at a place to rest outside the breeding season, especially in the winter, which can shelter several dozen individuals, so forming genuine roosting sites. In wintertime, the Northern Long-eared Owl takes a shower which is like a real ballet: it seems to be “dancing in the rain” as it exposes itself to the drops of water.
