Which of the following birds is explicitly permitted for hunting with a raptor?

The correct answer is American crows, which are one of the few bird species explicitly permitted for hunting with a raptor in certain areas. This management strategy is based on the ecological balance and regulatory frameworks that allow for a sustainable approach to falconry practices. American crows can be hunted because they are often abundant, and they can compete with other birds for resources, which can impact local ecosystems.

Crows are also seen as a suitable target for falconry because they present a challenge due to their intelligence and adaptive behavior, which can help to enhance the training and skills of both the raptor and the falconer. This type of prey can help falconers practice essential hunting techniques, as crows are savvy and often employ evasive tactics.

The other options listed, such as common ravens, goldfinches, and blue jays, typically fall under different regulations regarding hunting and are not considered permissible for hunting with a raptor. Each of these species has specific protections or regulations that limit their take, aiming to preserve their populations and role in the ecosystem.
