The falconer generally prefers the longwing to strike the lure...

A longwing, such as a falcon, is typically trained to strike the lure from a steep dive when flying downwind because this method allows the bird to utilize its aerodynamic advantages effectively. When a longwing dives downwind, it can take advantage of the tailwind, which helps the bird to reach higher speeds and maintain greater control during the strike. The additional speed and energy provided by the wind assist in delivering a powerful and accurate strike on the lure.

By flying downwind during the strike, the longwing can also enhance its visibility of the target and reduce the chances of being disrupted by wind resistance, leading to a more successful catch. This approach is more natural and efficient for these birds, which are adapted to high-speed pursuits in open environments.

In contrast, other methods, such as diving upwind, may create more resistance and may hinder the falcon's ability to reach optimal speeds and accuracy, making the downwind dive the superior choice for striking the lure.
