Which raptors are known to have a Malar Stripe to reduce glare from the sun?

The correct answer highlights the Kestrel and Peregrine falcons, both of which possess a distinctive malar stripe, a dark marking that runs from the eye to the beak. This adaptation serves a significant purpose: it helps reduce glare from sunlight, enhancing their ability to see while hunting.

By minimizing the effects of sunlight, these raptors are better equipped to spot potential prey even in bright conditions. The malar stripe effectively absorbs light, which can be particularly beneficial for birds that rely on sharp visual acuity for hunting and navigating through open skies.

The other options do not include species recognized for this particular adaptation. For instance, while owls and hawks have other adaptations, they do not typically exhibit a malar stripe in the same manner as falcons do. Understanding the features and adaptations of different raptors is critical for falconers and bird enthusiasts alike, as these physical traits enhance the birds' survival and hunting capabilities in their natural habitats.
