What it is

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.

Worth knowing

  • Males have a spectacular long, V-shaped tail.
  • They can be very noisy, especially when gathering in large groups.
  • They are very intelligent and can solve simple puzzles.
  • They sometimes 'ant' themselves by letting ants crawl on their feathers, which may help with parasites.
  • Their eyes are bright yellow.
  • Females are smaller and duller than males, with shorter tails.

Why it matters
