Attestations from sources in English:
ECA-TLOH-TLI, literally, “falcon of the wind god,” Aplomado Falcon (Falco femoralis) [FC: 44 Hecatlhotli] “It is the same as the falcon. It is named ecatlotli because its face is shot across with white. Its feathers are somewhat dark. It hunts in the same way as has been told {that is, for CUĀUH-TLOH-TLI}.” I believe this is most likely the Aplomado Falcon, which was once more widespread in northern Mexico (Howell & Webb). The face pattern of this species is characteristic.
