The sanctuary said it was “extremely unusual for wild birds to get into this condition naturally”.
Head falconer Rufus Samkin said: “Where she was found is very productive land, and it’s been a mild winter and there’s a lot of food around – voles, mice.
“We think she’s just done incredibly well for herself and overindulged.”
He said the owl lost between 20g and 30g over a couple of weeks while staff monitored its food intake.
“We may see her again – we hope not,” said Mr Samkin. “Hopefully, she’s learnt to keep her weight in trim so she can escape any predators or being picked up.”
