Why might wild haggard falcons be preferred by some falconers?

Wild haggard falcons are often preferred by some falconers because they represent wild breeding stock. Choosing a haggard falcon, which has reached adulthood and has already learned survival skills in the wild, provides falconers with birds that have not only genetic traits suited to hunting and survival but also the natural behaviors that come from their life in the wild. These traits can be beneficial when training the bird for hunting purposes.

The notion of wild breeding stock implies a genetic diversity and resilience that may not be present in captive-bred birds. Captive breeding can sometimes lead to inbreeding or the loss of important habitual traits necessary for hunting. Furthermore, haggard falcons carry the instinctual knowledge and skills developed through their natural upbringing, which can enhance the hunting experience and outcomes for falconers.
