I photographed this bird in Florida last month at a beach that had picnic tables. The bird was obviously used to having food thrown at it by the picnickers and probably also cleaning up after them. It was rather tame and while I was getting my equipment out of the trunk of my car, it kept watching me from the top of a nearby rock and even landing near me in expectation of some morsels. But I only took its pictures.
My meager birding talents did not let me identify it. So, I e-mailed the pictures to John, who writes A DC Birding Blog, and he identified it as a female boat-tailed grackle (Quiscalus major). Note that the males are black and look quite different than the females.
Also note how the bird was perched on that rock with one leg lifted up.
