What should you do if your male red-tail is mobbed by ravens and refuses to come to you?

If your male red-tail is mobbed by ravens and is hesitant to come to you, calling the hawk down with a tidbit can be an effective strategy. Tidbits are small pieces of food that can attract the hawk’s attention, enticing it to fly back to you despite distractions or stressful situations like being mobbed. This method capitalizes on the hawk's natural instinct to seek out food.

Using a lure, while also a valid option in many circumstances, is more typically employed when training or recalling a hawk during a less stressful situation. In this case, the stress and potential danger posed by the surrounding ravens make tidbits a more immediate and appealing incentive for the hawk to return to safety.

As for the other options, going to get a sleeping bag does not address the immediate need of recalling the hawk. While it may seem comfortable for the falconer, it doesn't serve any practical purpose in this scenario. Therefore, calling the hawk down with a tidbit is the most appropriate choice to effectively manage the situation with the mobbing ravens.
