Which raptor is least likely to nest on a cliff?

The answer identifies the Jack as the raptor least likely to nest on a cliff. This is based on the nesting behavior and habitat preferences of various raptors.

Jacks, or more commonly known as the American kestrel, typically prefer to nest in tree cavities, building ledges, or man-made structures, rather than on cliffs. Their nesting habits do not align with the cliff-nesting strategies that other raptors adopt. For instance, both the Golden eagle and Prairie falcon are known for their preference for cliff faces, where they can access ledges to create their nests, which offer protection from predators and easy access to hunting grounds.

Understanding the nesting behavior of different raptor species provides insight into their habitat preferences, illustrating why the Jack is less associated with cliff nesting compared to the others.
