What is a 'haggard' hawk?

A 'haggard' hawk refers specifically to a wild hawk that has reached maturity in its plumage, typically indicating that it has completed its juvenile feather development and is now exhibiting fully developed adult feathers. This terminology contrasts with birds that are still in their juvenile stages, which have not yet acquired the distinct plumage associated with their adult counterparts.

Understanding this classification is essential for falconers because it provides insight into the age and experience level of the hawk, which can affect its behavior, training requirements, and abilities when hunting. A wild hawk in mature plumage has also typically had the opportunity to gain necessary field experience, which might be vital for various aspects of falconry.
