HUĪTZITZIL-I/HUĪTZITZIL-IN/HUĪTZIL-IN, hummingbirds (Trochilidae) [FC: 24 Vitzitzili] “The bill is black, slender, small and pointed, needle-pointed, needle-like. In shrubs, in trees it makes itself a nest, it lays eggs, sits, hatches its young. It has only two eggs; its young are rare. Its food is flower honey, flower nectar. It is whirring, active [in flight]; ashen in color…. It flies, darts, chirps. In the winter it hibernates. It inserts its bill in a tree; [hanging] there it shrinks, shrivels, molts.” Despite the misapprehension with regard to hibernations and rejuvenation, this is no doubt a general term for the Núm.us species of hummingbirds of Central Mexico. Regional dialect variants include HUITZACATZIN [Xalitsa], HUĪTZĪQUI-TZIN [Zacapoaxtla], HUĪTZTZĪTZIQUIH [Tetelcingo], all noted in Karttunen). This term serves as the generic head term for 10 distinct kinds of hummingbirds (of 11 recognized and named). The specific kinds of hummingbirds are rarely described in sufficient detail to allow for positive identification, and I find several of Martin del Campo’s guesses to be wide of the mark. I believe it is best to leave several unspecified.

AYOPAL-HUĪTZIL-IN, literally, "purple dye hummingbird," perhaps the Violet-crowned Hummingbird (Amazilia violiceps) [FC: 24 Aiopalhujtzili] “… is light brown, the color of tunas {fruits of the prickly pear cactus}.” Martin del Campo identified this hummingbird as the Heloise, now Bumblebee, Hummingbird (Selasphorus heloisa). However, the sparce description does not support his identification. the combination of light brown and purple could describe the gray-brown back and violet-blue crown of the Violet-crowned Hummingbird, a common resident of the central Mexican highlands. See also HUĪTZIL-IN, hummingbird.

CHALCHI-HUĪTZIL-IN, literally, “jade hummingbird,” perhaps the Mexican Violetear (Colibri mexicanus) [FC: 24 Chalchihujtzili] “… is light green; a turquoise shade; herb-green." Martin del Campo identified this as the Broad-billed Hummingbird (Cynanthus latirostris), a quite reasonable option; however, I believe that species is more likely named XI-HUĪTZITZIL-IN. See HUĪTZIL-IN hummingbird.

Witsitsilin (El colibrí). "Un hombre descubre que todos los árboles que tumba están erguidos al siguiente día. Un conejo le dice que se trata de un pronóstico de que viene el diluvio. Al terminar el diluvio, Dios envía al zopilote a ver qué pasa en la tierra, pero éste se queda a comer cadáveres. Después envía al colibrí, el cual cumple con el mandato y, como premio, bebe la miel de las flores." (Escuchado en Ichcacuatitla, municipio de Chicontepec, Ver. Williams García, 1955, 4–5.)
