What tends to happen if a raptor shows uncontrollable jerking or twitching during handling?

When a raptor exhibits uncontrollable jerking or twitching during handling, placing it in a cool, dark room is a suitable response. These symptoms can indicate stress, fatigue, or overheating in the bird. By moving it to a cooler, darker environment, the raptor can recover from potential overstimulation and regain its composure. This action helps to reduce stress levels and allows the bird to stabilize without the added pressures of its surroundings.

In contrast, the other options do not directly address the immediate needs of the bird in this situation. Allowing the bird to fly free might exacerbate its condition, especially if it is disoriented or stressed. Providing more food could further disturb a raptor that is already in distress, as it may not be able to eat properly under these circumstances. Training the bird immediately would be inappropriate since the raptor needs time to recover before any further handling or training takes place.
