It's a Crow! Did you know they live in family groups, and return to the same spots year after year to nest? Odds are that a large group of crows is an extended family, not just random crows that have formed a murder! (AKA: Flock of Crows)
American Crow - The house crow has black body feathers glossed with metallic violet. Its wings are black with a green-violet gloss, and the eyes are brown. If threatened by a hawk or owl, flocks of crows will attack the larger predator.
Flock of Crows: Black birds set an unwelcoming scene when they alight around a doorway flanked with stalks of dried corn. There are two kinds of crows here: Some are cut from tar paper, a weatherproof material used in roofing, and others are artificial store-bought ones. Both perch on vines and pumpkins with the help of metal wires.
