So, what makes a raptor a raptor? What makes, say, a hornbill,

the shape of their bodies and beaks for one

What about secretaries, vultures, and condors? They certainly don't look like "traditional" raptors, yet they are classified as such.

a vulture with feathers on its face doesn't look very different at all from another raptor

the basic definition is a bird with good binocular eyesight that it uses to track prey, powerful hooked talons and a curved beak for tearing flesh. Storks and the like are excluded because of the lack of talons and curved beaks. But "raptor" isn't an actual taxonomic classification, and how they're all ordered depends on who you ask.

Taxonomically speaking not even owls and New World vultures such as condors are raptors.
But going by the common definition of what a raptor is,I'd say a raptor bird should have hypercarnivore diet, talons (which don't seem to be big enough on the hornbills) and curved and relatively shot beak.
