Can you explain to me why a bird of prey from a falconer mostly wear leather strings on their claws?
im so very fascinated in this kind of work you people do with those birds, it realy is beautiful to see.
i faved a lot, i saw that picture of a woman with a very big bird, and now this one a very small bird the Kestrel. my fav bird of prey is the Buzzard and Sparrowhawk, but then they are all so beautiful.
Now an owl is a bird of prey as well, can you train them as well such as falcons, eagles, hawks?
there is a beautiful movie "Ladyhawk" played by Rutger Hauer, the story is about a cursed man and woman who love each other very much, at day he is man and at night he becomes a wolf, at day she is a Hawk, and at night she is a woman...they go through life together though, the ladyhawk is sitting on the mans arm most of the day while he is kind of falconer......they are cursed because a jalous king dont want them to be together and that king wants to marrie her. the movie ends well. you've seen it? if not you should
