CLOSED: Completely black bird?

This bird was at our feeders today. It is completely black, feet, bill and eyes. It is larger than a sparrow and smaller than and cardinal. Puzzled by this one. Thanks in advance for you help.

This is more than likely a male, Red-winged Blackbird that got separated from his flock. In the winter, they will hide their red "epulates" which they display to impress the females and claim territory during breeding season. Normally, the bit of yellow is showing, but I did have a male last week who completely hid his wing color.

Ditto to Chillybean, the red shoulder is often hidden.

I had some Redwing Blackbirds on the feeder today. They are bigger than this bird was and the wing epulates were there. Some were yellowish and some were already red. Sorry I do not have a better picture.

Brightened the second pic - clinches it as a Brown-headed Cowbird. Note the thicker bill, and the brown on the head is visible (just!).

Thank you. I see the brown now.
