It always seems like Carson is frowning, but luckily that look doesn’t reflect her mood. Her apparently furrowed brow is built into her skull. Hawks and eagles have a prominent ridge that extends over the eye. This “supraorbital ridge” (supra = above; orbital = eye) acts like the visor on a baseball hat, shielding the eye from direct sun. Red-tailed hawks often soar high in the sky or hunt in open fields where there is little shade, so their built-in visor helps them see clearly on a sunny day.
Even if Carson looks angry while she soaks in the sun, she may very well be saying, “I AM smiling!”
