Which raptor is least likely to nest on a cliff?

The raptor that is least likely to nest on a cliff is the jack, commonly known as a jackdaw, which is actually a member of the corvid family rather than a true raptor. While some raptors, like the golden eagle and prairie falcon, are known for their propensity to nest on cliffs and ledges for safety and protection, the jack does not share this nesting behavior. Instead, jackdaws prefer nesting in trees, buildings, or other man-made structures. This preference for nesting sites contrasts sharply with the nesting habits of the other listed raptors, which tend to utilize cliffs to avoid ground predators and provide a safer environment for their young.
