Beak and foot shapes look good for an icterid. It's not an adult- I'd recognize it instantly if it were. Sub-adult something -- and it may not be possible to know male or female. Grackle seems like a possibility. I don't think the beak is heavy enough for brown-headed cowbird, which otherwise would be a decent match for color and pattern, and I don't think it's a red-winged blackbird, though I'm having trouble saying why - something about the face pattern, mostly. I believe the grackles at that location are boat-tailed and common. If I had to pick between those two, I'd guess boat-tailed. But don't quote me - I'd want to take a second look at other possibilities, like rusty blackbird (when do they migrate?).
