What is a common name for a person who specializes in flying short-winged hawks?

The term "shortwinger" is specifically used to refer to a person who specializes in flying short-winged hawks, such as the kestrel or the merlin. These birds have different hunting styles and behaviors compared to long-winged hawks. The skill set required to effectively train and fly these short-winged species often includes knowledge of their unique flight patterns and hunting techniques, which may differ significantly from those of larger or long-winged raptors. This specialization in the handling and training of such birds is encapsulated in the term "shortwinger," making it the correct answer to the question.

Other terms, such as "Hawker," can refer to anyone who flies birds of prey, regardless of the type or species. "Trainer" is a more general term that could apply to a range of individuals involved in animal training, not just those focused on falconry. The term "Austrian" does not apply in this context and does not represent a group associated with falconry or the specific practice of flying short-winged hawks.
