thank you.  I though it was a brewer's blackbird because of all the colors and iridescence on their back, but it's in new york city.

Grackles have larger bills and longer tails than Brewer's Blackbirds.  The one with the dark eyes and more brown color is a juvenile Common Grackle.

Welcome to Whatbird!

As another field mark, the purple iridescence on the head combined with bronze iridescence elsewhere is typical for mature male Common Grackles in most areas.  I think the purple interspersed with the bronze makes this a "Ridgway's Grackle", intermediate between the widespread purple-headed "bronze" form and the all-purple form.  Maybe.  Who took my old Peterson's?

The person to ask about COGR subspecies is @akiley.
