  • Size & Shape

    Boat-tailed Grackles are large, lanky songbirds with rounded crowns, long legs, and fairly long, pointed bills. Males have very long tails that make up almost half their body length and that they typically hold folded in a V-shape, like the keel of a boat.

  • Males are glossy black all over. Females are dark brown above and russet below, with a subtle face pattern made up of a pale eyebrow, dark cheek, and pale “mustache” stripe. Eye color ranges from dull brown along the western Gulf Coast to bright yellow along the Atlantic Coast.

  • These scrappy blackbirds are supreme omnivores, feeding on everything from seeds and human food scraps to crustaceans scavenged from the shoreline.

  • Boat-tailed Grackles are a strictly coastal species through most of their range; however, they live across much of the Florida peninsula, often well away from the immediate coast.
