Owls replace pesticides in Israel
Many farmers are installing nest boxes to encourage the birds, which hunt the crop-damaging rodents.
In Israel, where there is a drive to reduce the use of toxic chemical pesticides, this has been turned into a government-funded national programme.
Scientists and conservation charities from Jordan and Palestine have joined the scheme.
According to the charity BirdLife International, hundreds of birds of prey - including many endangered species - have been killed in Israel through eating rodents containing poisonous "rodenticides" sprayed on to crop fields.
