Attestations from sources in English: 

POXACUA-TL, (literally, “stupid,” Mexican Whip-poor-will (Antrostomus arizonae)” [FC: 46 Poxaquatl] “It is like the barn owl ; it looks like the barn owl. It is small, fluffy. As it flies, it only goes about flying erratically. Hence it is called poxaquatl. Dark yellow, dark yellow on the surface of its feathers.” This is certainly the Mexican Whip-poor-will (Antrostomus arizonae).
