CUĀUH-TLI (1) , eagle and/or large hawk in general (Accipitridae) [FC: 40 Quauhtli]: The base “CUĀUH-” serves as the head term for several distinct types of eagles and hawks, variously modified. It contrasts with TOH-TLI/TO-TLI, a general term for falcon-like raptors. Several of these specific kinds of raptors cannot be confidently equated with one or another known Mexican species, though Martin del Campo and I have made a stab at it, for better or worse. The Golden Eagle is the prototype and may be known simply as CUĀUH-TLI(2) or more specifically as ITZ-CUĀUH-TLI.

CUĀUH-TLI (2), Golden Eagle (Aguila chrysaetos) [FC: 40 Quauhtli] “The eagle is yellow-billed, very yellow… The bill is thick, curved, humped, hard. The legs are yellow, an intense yellow…. They are thick. The claws are curved, hooked. The eyes are like coals of fire. It is large, big. On its head, and neck, and on its wings. Ponn its wing-bends, and on its back lie feathers called cuauhtapalcatl… …. The eagle is fearless, a brave one…. a screamer, a wing-beater. It is ashen, brown.” This is the prototypical eagle/hawk, no doubt the Golden Eagle.
