Living in western PA I've been fortunate to see many presentations by Master Falconer, Earl Schriver.
A few things he has stated about birds of prey were,
They can kill an animal weighing 8-10 times their weight, they may not be able to fly off with it but they can and will kill much larger animals if hungry enough.
Think about what a 3lb falcon or 5lb hawk or owl can do?
If you have Golden Eagles in your area, you can have problems, they are such an amazing, efficient, predator.
One of the laws in falconry is no Golden can be free flown east of the Mississippi, beacuse if it's hungry, something big is going to die.
The female Golden he owns killed a full grown male German Shepard that killed a small falcon in the previous owners yard.
In times gone by, Golden Eagles were used to hunt wolves, one on one, their talons can crush a mans bones in the fore arm.
To actually see falcons, hawks, owls, and eagles up close gives a true respect for what they can do. The beaks and talons are truley scary, I've seen them, it's one of the reasons I didn't try and save my Barred Rock from a Great horned Owl a few days ago.
I knew she was dead when the owl landed, even at 6'2'' 240,,, I'm not fighting a wild box of razor blades.
Actually it was oddly beautiful and amazing at the silence and speed of how nature can work watching it from less than 20 yards away.
