Great-tailed grackle

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. Coyoltototl is the same as the acatzanatl, though some have a chili-red throat, breast, wings, rump. Some are yellow-breasted, very yellow-breasted, with white wing-bends. And very good, very clear, is its song—much like a bell, pleasing, sweet. Hence is it named coyoltototl. In the reeds, in the midst of reeds it sits, it hatches.
