The great-tailed grackle or Mexican grackle, (Quiscalus Mexicanus) is a medium-sized, highly social passerine bird native to North and South America. A member of the family Icteridae, it is one of 10 extant species of grackle and is closely related to the boat-tailed grackle and the extinct slender-billed grackle. Great-tailed Grackles can be found in open habitats with water nearby including farmland and city parks. Look for them in mixed flocks foraging on pastures and lawns—their long legs and massive tails distinguish them from other blackbirds and Common Grackles. Their diet is extremely varied, it includes many insects, spiders, millipedes, snails, crayfish, tadpoles, small fish, lizards, eggs and nestlings of other birds, and sometimes adult birds. They also eat a wide variety of seeds, waste grain, berries, fruit, and nuts. Great-tailed Grackles make an impressive array of sounds, ranging from sweet, tinkling notes to what one biologist described as “calls so loud they were best heard at a distance.” Other descriptions include “rusty gate hinge” and “machinery badly in need of lubrication.” The male’s territorial song includes a sound like crackling brush, a rapid-fire ki ki ki repeated 1–12 times, mechanical rattling notes, and a shrieking, high-pitched whistle. When ready to mate, both sexes give a “solicitation call” of clear cheat or che notes. Both males and females also make a low-pitched, hard chut alarm call, and males give a loud clack in response to humans and other predators. Females “chatter” when building the nest and when incubating eggs and feeding young. Here is a link so you can listen to this bird too!!!
