Great-tailed Grackle Identification

The Four Keys to ID

  • Size & Shape

    Male Great-tailed Grackles are long-legged, slender blackbirds with a flat-headed profile and stout, straight bills. The male’s tapered tail is nearly as long as its body and folds into a distinctive V or keel shape. Females are about half the size of males with long, slender tails.

    Relative Size
