The avian genus Quiscalus contains six of the ten species of grackle, gregarious passerine birds in the Icterid family. They are native to North and South America.

Etymology

From New Latin, quiscala, meaning "quail".[1] Grackle from New Latin, graculus, a daw or jackdaw,[1] where it originated in Europe, where it applied to starlings in the Old World.[1]

Description

The males have a glossy black plumage,[2] females are browner or greyer.[3] Both sexes have pale eyes.[2][3]

During breeding displays, the strongly graduated tail is held deeply keeled, giving a V-shaped cross section.[2] The keel-shaped tail of the Boat-tailed Grackle help differentiate it from the Fish Crow.[1]

Behaviour

Taxonomy

There are seven species of grackles, one of which is now extinct, the Slender-billed Grackle.[2] It was found in Central Mexico and hasn't been seen since 1910.[2]
