It's generally not recommended to touch a stunned bird, as they can carry diseases. Additionally, handling a stunned bird can cause further stress or injury, and may interfere with the bird's ability to recover. However, if you must handle a stunned bird, wear gloves and handle it gently, using a towel or a soft cloth to keep it warm. Keep the bird in a quiet, dark and warm place until the bird recovers or until you can transport it to a veterinarian or a wildlife rehabilitator.
