If your Red-tailed Hawk refuses to come down from a tree and you are forced to leave it out overnight, what should you do next?

The correct choice emphasizes a comprehensive approach to dealing with the situation of your Red-tailed Hawk being stuck in a tree overnight. Arriving before dawn to attempt recovery allows you the opportunity to retrieve your hawk while it is still vulnerable and potentially less active, increasing the chance of a successful recovery. Additionally, contacting your sponsor for advice is a vital step. Experienced falconers often have insights or strategies tailored to specific circumstances that can be helpful and informative.

Taking these actions not only demonstrates responsible falconry practices but also reflects an understanding of hawk behavior after being left out overnight. While setting up a bow net could be a strategy for recapturing, it is essential to focus first on direct recovery efforts and seek guidance from an experienced mentor, which is why options A and C form a recommended course of action.
