The largest of the three North American grackles, Great-tailed Grackle is distinguished from Boat-tailed Grackle by its larger size, l0nger tail, flatter forehead, and more western range (although the ranges overlap along the Texas and Louisiana gulf coasts). Females are grayish brown, smaller, and lack the namesake huge tail.

Thanks so much I was able to satisfy my curiosity. Just saw a whole group of them at a rest stop in Kansas mile marker 17?
