"Owls are an order of birds of prey. Most are solitary, and nocturnal, with some exceptions. Owls have large forward-facing eyes and ears, a hawk-like beak, and usually a conspicuous circle of feathers around each eye called a facial disc."
Yep. That's the text of the ad. The poster has apparently had trouble unloading this free collection of owls, and has decided he knows the reason: none of you ignorant freaks know what owls are.
Now that you do, perhaps you'll finally get in your car and pick them up.
