Male Harris's can and will take all quarry the females can, with the exception of brown hares. I personally do not like flying brown hares with Harris's, due to the size and power of this quarry there is a very real risk of serious injury or even death to the bird. You'll certainly have more fun with a male and they are more ameanable. Start with a young bird and if you have not already done so, get yourself a mentor! If this is your first bird I hope you have got everything in place, Equipment, Food, shelter etc..... and that includes practicle experience BEFORE you get the bird. Good Luck!
