IZTAC-TLOH-TLI, literally, “white falcon,” Prairie Falcon (Falco mexicanus) [FC: 44 Iztac tlhotli] “Its name is sacre . It does not hunt ducks much ; it wars upon hares, rabbits, turkeys, and chickens. It is called “white falcon” because its feathers are pale striped with white. It always hunts … by day…. Its legs are yellow.” Perhaps yet another name for the prototypical falcon, the Prairie Falcon.
