Conservationists at the Cumbria based World Owl Trust believe that this year's exceptionally cold and wet spring has impacted on the breeding season of the UK's owls.
Experts at the world's leading owl conservation centre say that owls which would have normally hatched owlets by now are still sitting on eggs.
Wulf Ingham, head keeper at the World Owl Trust, said:
“We are well behind where we would normally be in terms of the breeding season.
“We think it is due to the cold and wet spring that we have had this year.
"Our officers who go out monitoring barn owls have reported that they have not yet been able to record any owlet numbers because none of the owls has yet hatched any owlets.”
The World Owl Centre, based at Muncaster Castle, is home to owls from around 40 different species and sub-species.
Conservationists at the Trust have been working to ensure that endangered owls are kept safe, and their rehabilitation unit nurses injured owls back to full health.
