Final answer:
Hawks have excellent day vision and can see ultraviolet light; however, their night vision is poor, and contrary to the incorrect statement, they do not have a keen sense of smell. The correct option is d.
Step-by-step explanation:
The question seeks to identify the incorrect statement regarding the eyesight of hawks. Hawks are known for their excellent day vision, which allows them to see up to 8 times more clearly than humans.
This remarkable vision enables birds of prey, including hawks, eagles, and falcons, to effectively hunt by sight, observing potential prey from great distances. Regarding their night vision, it is generally poor compared to other animals like owls, which possess superior nocturnal sight.
Additionally, like many other birds, hawks can see ultraviolet light, which aids them in detecting the urine trails of prey and other signs that are invisible to humans. However, hawks do not have a keen sense of smell, which is a sensory characteristic more associated with other animal groups. The correct option is d.
