Ivar is Mr Mcpherson’s first bird of prey and he has trained her since buying her at sixteen weeks.
The plumber said he had gone “above and beyond” to care for her, spending hours of contact time taming her into an approachable feathered companion.
“I couldn’t have asked for a more solid bird from all the manning I’ve done,” he said.
Mr Mcpherson had ambitions of taking her to shows, presentations, and forest walks, but that has been scuppered by the flying session at the recreation ground.
“She got into a bit of bother with the gulls and the crows. They started getting on top of her and bullying her off,” he said.
Ivar had consistently responded to her name, Mr Mcpherson’s voice, glove and whistle call, but having acted on sightings since the incident, the owner thought some of that training had been undone.
“She sees me, I go up to the tree, I call her, and I get no response,” he said.
He said he fears the hawk does not have the hunting skills to feed herself in the wild and could continue to be outmuscled by other birds.
However, Mr Mcpherson is still hopeful his bird will return to the glove, having read of harris hawks being retrieved after months away from their owner.
He has thanked people who have reported sightings and falconer friends who have used thermal image cameras and dogs to locate her.
“The response I’ve had has been brilliant,” he said. “There’s definitely hope, especially with all these new sightings.”
