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

@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
