Which raptor is not legal for falconry?

The Osprey is not legal for falconry primarily because it is classified as a fish-eating bird and does not belong to the traditional group of raptors that are permitted for falconry practice. In the context of falconry, regulations dictate specific species that can be used, generally favoring those that exhibit the hunting, training, and domestic characteristics desirable for this activity.

Meanwhile, the other birds listed, such as the Gyrfalcon, Harris's Hawk, and Peregrine Falcon, are recognized as suitable for falconry. These species have been historically utilized in the sport and are known for their hunting abilities and trainable natures, allowing falconers to engage in the practice effectively. The breed characteristics of these raptors align with the goals of falconry, making them legal and popular choices among falconers.
