Attestations from sources in English: 

ZŌL-IN/ZŌL-LI, Montezuma Quail (Cyrtonix montezumae) [FC: 49 Çolin/Çolli]: “Its bill is pointed, ashen-green. Its breast is spotted with white; its wings are called chia-spotted. It is a runner…. It has eggs. When it lays eggs, when it hatches its young, it lays forty eggs. It hatches indeed fifty young. It food is dried grains of maize, chia, and xoxocoyolteuilotl.” Martin del Campo identified this bird as the Montezuma Quail. Though there are perhaps four species of quail that live near or in the Valley of Mexico, this species best fits the description. Of the local Central Mexican quail species, only the Montezuma is distinctly spotted. The Montezuma Quail is known to lay up to 12 eggs, but females may adopt neighbor’s broods. Males (TECU-ZOLI) and females (OHUATON) may be distinguished nomenclaturally.
