I would have thought the same thing before I got into horses. Now, horses are lightyears away from raptors in that horses are social animals. However, most horses are always going to prefer the company of other equines to that of humans. They’re not at all like dogs or cats. If I’m truthful, I’d have to say my horse tolerates me and knows I bring good things (usually edible), but she doesn’t love me and likely never will. It’s just not in her make up. And you know what? I’m fine with that. She is who and what she is. I can love her just fine. It doesn’t have to be returned with an animal.
Nava, I noticed you said one of the risks you encounter is that your bird will decide to fly away and not return to you. How long do most falconers keep their birds? Is it a lifetime thing for the bird, or do you anticipate that some day Arion will say “see ya” because he’s found a cute lady red tail giving him a come hither look?

The thing is, I don’t love my bird in the way that I love my dog or my cat or my spouse. I have a vast amount of respect and admiration for him and a huge desire to hold up my end of the bargain in our partnership, but it’s definitely a partnership rather than a loving, pet-type relationship. He works for me because I make it worth his while to do so, and I consider it a tremendous honor and privilege that he does.
How long folks keep their birds is entirely dependent on the particular situation. Some people will trap and train a new bird every year, releasing them at the end of the season (sometimes these birds show up again the next year, ready to hunt), some folks will train a bird through several seasons then release once they’ve accomplished their goals, some folks will keep a bird for life. Some will transfer birds to another falconer or release them when they decide to pursue other quarry with a different species or just to take on the challenge of training, say, an accipiter instead of a longwing or whatever. Sometimes, especially early in the trapping season, you trap a bird that ends up being dumb as a box of rocks and the relationship ends quickly. Sometimes you end up with an ideal hunting partner and you hunt together for decades.
An apprentice is allowed to hold one bird, only, at a time,* so if I wanted to pick up some experience with longwings I could release Arion at the end of the season and trap a kestrel for next year, but I couldn’t hold both at once. My intention as a general falconer is to trap and train a ferruginous hawk and hawk her from horseback. In that situation I may keep and continue to fly Arion after quarry that ferruginous hawks are too slow and clumsy to hunt. A good RTH is an astonishingly good hunting partner; apprentices in the US are extremely privileged to have access to them. Folks in other countries would give their eyeteeth to be able to trap a passage RTH for falconry purposes. They are brave enough to hunt foxes, agile enough for squirrel hawking, versatile and game enough to hunt just about anything you’ll flush for them–unlike many species which are so tuned-in to one type of prey, they won’t even look at anything else.
It’s hard to say whether or not he’ll decide some day to just take off. Some do, some don’t. Some keep coming back whether you like it or not ;). We stack the deck in our favor by keeping him hungry and focused on me as a source of food and prey. When they’re fat and comfy and their immediate needs are totally satisfied is when it’s most likely for them to disappear, though this is more a concern in the first year or two. After the relationship is well-established, sharp combat weight is less a concern. But in the end… they are wild animals and they are free to go if they please, and sometimes they do.
*General falconers are allowed to hold two birds on their falconry license, and masters three, at least in my state.
