Great-tailed Grackle

Quiscalus mexicanus

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The great-tailed grackle is an icterid with a long, keel-shaped tail and black plumage with violet sheens in the male, much smaller and brown in the female. It is one of the most characteristic urban birds of Mexico and Central America, where it fills the plazas at dusk with deafening roosts. Its range has expanded enormously over the past century, following agriculture and cities northwards.

Fun facts

  • It has expanded its range spectacularly over the past century: in 1900 it barely reached southern Texas and today it breeds as far as Canada, following irrigation and built-up areas.
  • Its vocal repertoire is among the most varied and strident in the Americas: whistles, clicks, metallic shrieks and sounds like machinery, all from the same bird.
  • Mexican tradition holds that the grackle stole its seven songs from the sea, and that is why it has seven different voices.
