Attestations from sources in English: 

ĀCA-TZANA-TL, literally “reed grackle,” Slender-billed Grackle (Quiscalus palustris) [FC: 50 Acatzanatl/Acatzunatl] “Some are quite black, some only smoky. They dwell among the reeds; among the reeds they hatch. They prey especially upon maize, and worms, and the small insects which fly.” Martin del Campo fails to distinguish this from Tzanatl, the Slender-billed Grackle. It is possible this is a synonym for that species, as distinct from the larger, introduced Great-tailed Grackle, known as Teotzanatl. Both species of grackle are at home in the reed beds. However, it might also be a synonym for COYOL-TŌTŌ-TL, Red-winged and Yellow-headed Blackbirds.
