You lure fly an eyass female peregrine falcon and she strikes the lure firmly on her first stoop of the day. You should...

Feeding a reward to the eyass female peregrine falcon after she successfully strikes the lure reinforces her behavior in a positive way. This immediate reinforcement ensures that she associates the reward with her successful strike, which encourages her to repeat that action in the future. Successful training hinges on the ability to provide timely and appropriate rewards for desired behaviors.

In the context of falconry, particularly with a young bird like an eyass, reinforcing the correct behaviors early on is crucial for building a strong positive relationship and ensuring effective training. By rewarding her with the lure, you are acknowledging her success and promoting her confidence as a hunter.

Other choices do not align with effective training practices. Swinging the lure while ignoring her successful hit does not provide any reinforcement; instead, it could lead to confusion or discourage her from performing that behavior again. Withholding the reward after a successful strike is counterproductive, as it can create uncertainty about what behaviors are being rewarded. None of the alternatives promote effective training, while offering the lure and rewarding her aligns with the principles of positive reinforcement.
