The Great-tailed Grackle or Mexican Grackle (Quiscalus mexicanus)
Males reach up to 43 cm (17 in), including a tail that is almost as long as the body, weigh 230 g, and are jet-black with a violet-blue iridescent sheen to the feathers. Females are significantly smaller at 33 cm (13 in), weigh 125 g, and are mainly brownish-black, with a pale brown throat and belly. This morphological difference between males and females of a species is known as sexual dimorphism.Wikipedia
