"I think it's a hyena," said 12-year-old Glyndon resident Mitchell Jones about a weird-looking animal seen lurking around Glyndon the past few weeks. "It's really freaky."Sighted by a few residents in the leafy, well-tended backyards along Butler Road, the animal is said to be about the size of a small dog, with no fur, except for a scraggly bit on its head and running down its spine.Central Avenue resident Jay Wroe spotted the animal in the backyard of his parents' home in the 4800 block of Butler Avenue.Wroe works for the family electronics business, which is headquartered in a large garage on the property. He said he saw the animal in a field one afternoon and wondered, "What in the world is that?"Being an electronics technician, he set up a motion sensor to ring a bell in the garage. And he kept his video camera handy.Wroe said the bell rang last Monday and he ran outside, camera at the ready. He captured about five minutes of video footage of the animal roaming around and rooting in the grass."When I first saw it, I went and got some more witnesses. I tried to track it a little bit, but it goes back through the big field over there," he said pointing to an adjacent property.Wroe said his neighborhood has all the usual kinds of wildlife, such as deer and groundhogs, "but nothing this wild. Nothing this bizarre.""It's either a hyena, or a sick-looking fox," he added.Neighbor Marie Cole has lived in her secluded Glyndon home for 55 years.She said the animal sat in the middle of her yard the other day as she mowed the lawn around it."He just sat there and looked at me," she said. "It's a fox with no hair, except on its head. I figure he's got rabies or something."Cole said she's seen red foxes on her property, usually in the fall."They got a pretty red coat and they don't stop and stare at ya'. They're on the move," she said.Wroe said a wildlife expert at the Gwynnbrook Wildlife Management Area in Owings Mills looked at his videotape and declared it a fox with mange.
