Walking to class everyday in the afternoon at St. Edwards, my buddy and I see numerous black birds near the parking garage. Some of these are known as the Great-Tailed Grackle, Quiscalus mexicanus. They are commonly seen in suburban areas foraging for insects in lawns. The males have black iridescent and purple feathers with bright yellow eyes. They are known for their loud vocalizations, which sometimes categorizes them as a pest species.
