I've heard of them eating about anything that moves from baby alligators and birds to rabbits and snakes. Apparently they have been known to fight each other to the death in territorial disputes. I watched one chase a cat for ten minutes. Started with the cat stalking the heron but the table was soon turned. I just can't think of any bird as vicious as a GBH. Maybe some African birds may compare..
Snowy Owls can and will kill just about any bird, that includes Great Blue Herons, Short-eared Owls and even other Snowy Owls.
Here in the Boston area there was a female Gyrfalcon that spent two or three winters near Logan Airport. One of my contacts with Mass Audubon watch this Gyrfalcon (A VERY LARGE FALCON) dive on a Snowy Owl......big mistake, on the second pass the Snowy Owl turned and clipped the Gyr then chased it for as far as could be seen with 8x Swarovski binoculars!:eek:
That's the other thing about Snowy Owls they are MUCH faster then most people think.
Arlon, No need for that. We are all here to learn from each other. There is no such thing as a dummy question. It is only a dummy question if never asked. From reading this thread I've learned a couple of things.
