XI-HUAPAL-QUECHOL, Turquoise-browed Motmot (Eumomota superciliosa) [FC: 21-22 Xioapalquechol] “Its name is also tziuhtli. The bill is long. The legs are black. Its head, and its back, and its wings, and its tail are light blue; its belly and its wing-bend tawny. It becomes green, it is green; it becomes tawny, it is tawny.” Martin del Campo identified this bird as the Turquoise-browed Motmot (Eumomota superciliosa). Given that the Aztec scribes describe the Lovely Cotinga as a resident of Anáhuac, inclusive of towns in coastal Chiapas (Martin del Campo), it is possible they were familiar with the Turquoise-browed Motmot, as its limited Mexican range includes the Yucatan Peninsula and the Pacific Coast of Chiapas.
