She doesn't look like she's starving, House Sparrows have been living in warehouses & even the Detroit airport for years
If there's a food & water source, you may have Sparrows for good
i would not expect her to take Pop Tarts from the hand ??? but her calmness to your approach suggests to me that somebody's been feeding her (maybe on the sly)-- probably they drop the crumbs for her to pick up instead of trying to hand feed her tho
not sure where they saw it, but if i saw it around here, i'd call it as Common Grackle
they do have that amount of brown but it's a play of light type of thing where most of the time they just look like an all-over black bird until the light is striking their plumage at the right angle
