The Long-eared owl (Asio otus) is a medium sized owl. These nocturnal hunters roost in dense foliage, where their camouflage makes them hard to find. Head feathers (known as ear tufts even though they are not ears) raises when alarmed. Long-eared Owls are nimble flyers, with hearing so acute they can snatch prey in complete darkness. Between 2008 and 2010 photos of Long-eared owl for article for National Geographic Slovenia magazine were taken.
