TLĀLA-CUEZA-LI, Red-crowned Amazon (Amazona viridigenalis) [FC: 23-24 Tlalacueçali] “It is a forest-dweller, with curved, yellow bill, a chili-red head, purple-brown wing-bend, dark yellow breast. Its back, wings, tail are dark green.… Its tail and wings are leaf-colored.” The description best fits the Red-crowned Amazon, which has an extensive red crown and a yellow bill, features less obvious in the other four Amazona species in the vicinity of Central Mexico. I agree with Martin del Campo ’s identification.

The orthography of this bird name varies, sometimes ending in -li, sometimes in -lin. Perhaps the -li ending is inadvertently missing the final -n. Both spellings appear in the Gran Diccionario del Nahuatl:
