Why are haggards (adults) not taken for falconry?

Haggards, or adult birds of prey, are typically not selected for falconry because they play a crucial role in the breeding population of their species. Allowing these mature birds to remain in the wild ensures that they can reproduce and contribute to the genetic diversity and overall health of their populations. In essence, protecting the adult breeding stock is vital for conservation efforts, as removing haggards from the wild can lead to a decline in their numbers and disrupt ecological balance.

While the other reasons may have some validity, they do not capture the primary concern related to conservation and the role of adult birds within their ecosystems. The focus on preserving breeding individuals highlights the importance of maintaining healthy wildlife populations, which is a fundamental principle for responsible falconry practices.
