Eurasian Tree Sparrow is the full common English name of this species

there are 2 large groups of sparrows, Old World & New World, your Eurasian Tree Sparrow is an Old World Sparrow while American Tree Sparrow is a New World Sparrow that is not too closely related

so... yes ... there are MANY kinds of sparrows + to add more confusion, non birders sometimes call any small brownish bird a sparrow

@StarvingMartist

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

(males have gray crown & black bib)

@snlug

"i would have laughed if you told better jokes"-- grimly serious Laughing Falcon, probably

(PS- love these birbs!)

@streetfestival @imcan8dn

they do look a lot alike but the lack of the black bar beneath the white wingbar makes this bird a Hutton's Vireo

there's a good comparison pair of photos at this link
