White-tailed Hawk, a bird (see Hunn, attestations)
IZTAC-CUĀUH-TLI, litearlly, “white eagle/hawk,” White-tailed Hawk (Buteo albicaudatus) [FC: 40 Iztac quauhtli] “It has scant, ashen [feathers]; it lacks down; it is very chalky. The bill is yellow, the legs are yellow.” This name might apply to a variety of large diurnal raptors. The White Hawk (Leucopternis albicollis) is nearly pure white but has a dark bill, while the White-tailed Hawk is white below and on the tail, with yellow bill and legs. Both are large hawks, though the White-tailed ranges more widely, notably in highland areas of northern and central Mexico (Howell & Webb).
