A real life game of Angry Birds is playing out between a Newfoundland homeowner and an unusually aggressive pair of ravens.

Johnaton Poulain said the destructive duo has left blood stains on the window frames of his newly built Harbour Breton home. He figures he will have to replace 10 planes of glass and one screen because of the relentless pecking, pounding, and dive-bombing.

“They’re desperately trying to get in,” Poulain told NTV on Tuesday.

Video posted to Facebook shows one of the large black birds marching back and forth in front of a second-story window, pausing to peer inside the home and smashing the glass with considerable force.

At one point, a raven defiantly stands on top of a fake owl mounted near the window to keep the birds at bay. The seven-minute clip has been viewed more than 4,000 times in less than 24 hours.

Local wildlife officials said they have never seen anything like it. But social media commenters have espoused a number of theories to explain the bizarre bird behaviour.

Some have suggested it may be a mother who laid eggs inside the home during its construction. Poulain thinks they feel threatened by the sight of their own reflections.

“We moved in in December. I was around when the house was being built. I don’t think that it is actually possible that there are any nests inside the house,” he said. “I think they are seeing their reflection in the window, and they are going all out.”

Poulain said he found the situation so disturbing that he flew home from Fort McMurray, Alta., where he works, after a neighbour sent him the now-popular footage of the ravens scratching at the seals around the window and trying to bash their way in.

“I got a video sent to me a couple of days ago. I had no other choice but to come home,” he said. “My house was being attacked by ravens.”

Poulain said the birds fly off when he is home and return when he leaves the property. None of his neighbours’ homes seem to be under siege, but there have been some reports of vehicular vandalism.

“We get black crows down our way. They are terrible too,” said neighbour Francis Nichol. “They will peck your (car) roof.”

With the war of birds escalating into an Alfred Hitchcock-style conflict, Poulain said he has no other option to appeal to a higher power. He has contacted a priest about having the house blessed.
