What is the most important factor in determining which raptor a falconer should fly?

The most important factor in determining which raptor a falconer should fly is the availability of prey suitable for that raptor. This is crucial because a raptor's diet directly influences its health, training, and overall success as a hunting bird. Different species of raptors have specific prey preferences and hunting styles. For example, a falcon might hunt small birds, while a hawk may prefer rodents or larger birds. If the falconer cannot provide appropriate prey, the raptor may struggle to hunt effectively, potentially leading to health issues or a lack of hunting success.

While housing and proximity to other falconers can affect a falconer's experience, they are secondary to ensuring that the raptor has access to suitable food sources. Ultimately, a falconer's priority should be to meet the biological and dietary needs of the raptor to ensure a successful partnership in falconry.
