COCHO/COCHO-TL, White-fronted Amazon (Amazona albifrons) [FC: 23 Cocho] “It resembles the young yellow-headed . It has a yellow, curved bill; it is crested. Everywhere [over its body] its feathers are dark green; its coverts are dark red [and] dark yellow…. It is a singer, a constant singer, a talker, a speaker, a mimic, an answerer, an imitator, a word-repeater. It repeats one’s words, imitates one, sings, constantly sings, chatters, talks” (23). Of the Mexican parrot species, those of the genus Amazona are best known as mimics. The largest, the Yellow-crowned Amazon (Amazona oratrix) is TOZ-TLI, with the young birds of this species – hand raised – further distinguished as TOZ-NENE. It is also “a talker.” The Red-crowned Amazon (A. viridigenalis) is distinguished as TLALA-CUEZA-LI. That leaves four candidates for this name: Lilac-crowned (A. finschi), Red-lored (A. autumnalis), Mealy (A. farinosa), and White-fronted. Martin del Campo opted for the smallest of these species, the White-fronted, known then as the White-fronted Parrot. I see no reason to dispute this.
