Long-eared owls are highly secretive and poorly surveyed but face habitat loss from forest management.
Long-eared owls face welfare challenges from forest clearance that removes nesting habitat. Their secretive nature means population trends are poorly known making welfare assessment difficult. Secondary rodenticide poisoning from eating contaminated voles and mice causes internal haemorrhage. Communal winter roosts can be disturbed by birdwatchers causing energy waste and stress.
