Starlings are highly invasive in the USA and these formations can be enjoyed there too -- I've read of Central Park NYC and Seattle both seeing them.
Cool story, until just recently, it was commonly believed that starlings were first brought to the USA in 1890 as part of a Shakespeare fan's project to introduce all of the birds mentioned in his works. But I just looked it up, and now it looks like scholars are finding little evidence for that story!
