Why are jacks considered difficult prey for raptors?

Jacks are considered difficult prey for raptors primarily due to their exceptional agility and evasive maneuvers. They possess remarkable abilities to dodge and weave, making it challenging for raptors to successfully capture them. This skill set enables jacks to react quickly to threats, increasing their chances of escaping an attack. While size, speed, and defenses may also play a role in the dynamics between prey and raptors, the primary concern when it comes to hunting them is their capacity for evasiveness and quick, unpredictable movements, which can easily frustrate and thwart a predator's attempt to catch them.
