This bird was with a large mixed flock of birds including Brewer's Blackbirds and Red-winged Blackbirds, and was about 25% larger than Brewer's Blackbirds, with much thicker, longer bill held in more upward position. Coloration on head and extending down into breast area was a dark greenish color, and was sharply delineated from coloration on rest of body, which was brownish-bronze color. Eyes were light yellow. Tail was not as long as a Great-tailed Grackle's tail, but was longer than a Brewer's Blackbird's tail, and was tapered at the end.
