Great-tailed grackle (Quiscalus mexicanus)

Males are up to 43 cm in length (with a tail almost as long as its body), weights 230 g, and are black with an iridescent luster. Females are smaller; they measure up to 33 cm in length, weigh 125 g, and are brown.

They are very successful and intelligent, capable of opening bags and cardboard boxes in search of food. They tend to intimidate smaller species and defend their nests aggressively by clicking an alarm that puts others on alert. This bird has a unique song to conquer the female, which is strident and is accompanied by a dance in front of the female, opening his wings and jumping.
