grackle,

common name applied to some members of the New World family Icteridae, which also includes blackbirds, orioles, meadowlarks, cowbirds, and others. The plumage of the purple, or common, grackle of the Atlantic coastal region is black with metallic hues, iridescent in the sunlight. It feeds on grain and harmful insects, but it is a cannibalistic nest robber. Grackles invade cities and roost in huge flocks. The bronzed grackle, which interbreeds with the purple, is found further inland and W to the Rocky Mts.; in the South are found the Florida and boat-tailed grackles, in Texas and Mexico the great-tailed grackles, or jackdaws. Grackles are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.
