Animal rescuers hope to be able to release the swan back into the wild

Jim and Isabel Ballantyne were given the "biggest shock of their lives" when they saw the bird sitting at the side of their bed.

It is thought that the male cygnet lost its bearings and mistook the upstairs window's reflection for a pond.

The bird survived the ordeal with cuts to both of its feet.

'Amazing survival'

Mr Ballantyne, 71, from Bridge of Weir, Renfrewshire, said: "We both got such a fright, we couldn't believe our eyes at first."

The couple had been babysitting their six-year-old grandson Ryan when the swan made a dramatic entrance to their home.

They were in the living room when Mrs Ballantyne heard a loud bang followed by breaking glass at 2300 GMT.

Her husband rushed outside to discover their bedroom window had been smashed.

I would have thought that he would have broken his neck when he hit the thick glass, but he was fine Mrs Ballantyne

Mrs Ballantyne ran upstairs to check their room and said she could not believe her eyes.

"I opened the door and shouted to Jim when I saw the bird sitting there. It was surrounded by glass and there was blood everywhere," she said.

"We would normally be in bed, but because Ryan was over we were still up.

"Thank God - I can't imagine what would have happened if it had landed on us.

"I am absolutely amazed that he survived the smash. I would have thought that he would have broken his neck when he hit the thick glass, but he was fine."

The couple wrapped the dazed bird - nicknamed Magoo - in blankets and, on the advice of a vet, contacted Hessilhead Wildlife Rescue Trust.

Workers scooped the bird into a special bag and took him to their centre in Beith, Ayrshire.

Founder Gay Christie said: "He had a cut on one eye and his feet were bleeding badly.

"Both have now healed so we are hoping that he can be released back into the wild as soon as possible.
