My friend is convinced there is a bear in the woods outside his house. He hears it growl late at night and it scares the beejeezus out of him. I have assured him that it's not a bear, but he doesn't believe me. I think the sound he hears is a bird. Perhaps an owl, nightjar or egret (shorebird). Can anyone help identify this mysterious bear-bird? What bird might make a sound like a growling bear?
