It can be confused with the similar-looking and similarly named short-eared owl, particularly when the long-eared owl has its tufts of feathers laid flat on its head. However there are some key identification features to tell the difference between the two species.
I've been monitoring these owls for a while and happy to say that the two chicks are doing well, they have developed their adult feathers and no longer look like grey fluff balls.
Long-eared owl (male): The long-eared owl is one of four native owls in the UK, and one of five resident species here (the additional non-native resident species is the little owl).
During the owls breeding cycle, it is the male that does most of the hunting; depositing prey at the nest before egg-laying begins, providing the female with sustenance during incubation and providing the bulk of the prey for the young birds.
