TLĀUH-QUECHŌL/TLĀUH-QUECHŌL-LI, Roseate Spoonbill (Platalea ajaja) [FC: 20 Tlauhquechol]: “Also its name is teoquechol. It is a waterfowl, like the duck: wide-footed, chilli-red footed. It is wide-billed; its bill is like a palette knife. It is crested. Its head – as well as its breast, on its belly – and its tail, and its wings are pale, pink, whitish, light-colored. Its back and its wing-bend are chili-red.… The bill becomes yellow…. the bill becomes wide; the legs become yellow…. chili-red….” A detailed description of the Roseate Spoonbill. The American Flamingo (Phoenicopterus ruber) might fit as well but is restricted to the coastal lagoons of the Yucatan Peninsula. Karttunen notes that, “QUECHŌL refers not to the color of the bird but apparently to the characteristic sweeping motion of its neck .” This may be relevant also to the motmots named XIUH-QUECHŌL and XIUH-PAL-QUECHŌL, as they “twitch their tails from side to side” (Howell & Webb).
