Harris said it was still adjusting to not having binocular vision, making it difficult to catch prey or land.
“There’s a bit more green around the eye, so I’m hopeful that he may regain his sight.
“It’s just going to be a time thing.”
Her passion for rescuing owls began after she saw one sitting on a power pylon.
She was struck by how majestic it looked.
Harris told a friend who looked after the aviaries at Queens Park in Invercargill, who said chicks and injured owls were dropped off every now and then.
“I said I’d love to raise one, so she said I’ll send the next lot round to you; so she did and that’s where it all started.”

The busiest time of the year is in early summer during the hatching season.
This is when people often come across owl nests while cleaning up woodpiles.
“They’re cavity dwellers – well, some put nests in trees, but a lot of them would just find a cavity and that’s where they have their chicks.”
More often than not, the chicks end up on Harris’ doorstep, and once they can master a test flight down her hallway, they go out to an aviary until they’re up to weight.

“Then I pull down this soft release door, and when the owl’s ready to go, they’ll look at me; they’re a bit suspicious and then they fly away,” she said, showing Country Life around the aviary.
Harris said there were only three species of owls in Aotearoa New Zealand.

“Officially, there’s two classes of native owls.
“You’ve got the morepork (ruru) and the little owl (ruru nohinohi); we’ve also got barn owls and, apparently, there’s a bit of a flock of them up in Auckland now.”
