I lost a bird a while back to a large predator bird. I got a quick look at it when it dropped the hen & landed on our old tractor about 20ft from me. I probably should have posted this sooner but I remember it being ver dark, almost black with some long, line looking whitish feathers down its chest, I didnt get a chance to get a good look at the beak or face because it flew off when i jumped the fence to get the hen. i looked up hawks but the colors didnt match the bird i saw. anyone else ever seen one of these? the closest i could find was red tailed hawk, but the colors still aren't right. The property we own is almost half hillside, very steep, wooded, and thick in areas, it's inhabitants range from deer, elk, coyotes and many other small rodent-type critters, we have both bald eagles & hawks around here also, a lot of them, we've never had a problem with any birds of prey until the last couple years. we had a hawk (she thinks, i didnt see it) try & grab one of our dogs out of the middle of the field a long time ago but this chicken attack was the first bird loss we've had to predator birds. I still can't figure out what breed/species of hawk it was, it certainly was not an eagle though, i probably would have had a heart attack, lol. We put up fake owl statues & haven't had a problem since but i'm still baffled as to what it was.
