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
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)
@GlassHalfHopeful @Peanutbuttergrits
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
@JubilantJaguar
looks like they all have food, maybe someone is feeding them...
i never see the New Orleans monk parakeets all that close... SIGH
