both the invasive house sparrow and the starling were introduced in the Americas from Europe in 1890 by a German immigrant named Eugene Schieffelin.
He was a member of the American Acclimatization Society, which aimed to further colonize America with European plants and birds.
These birds are responsible for the decline of native species including the red headed woodpecker, purple martin and bluebird, and thus are not protected by the Migratory Bird Treaty Act of 1918
@Coffee_and_Salt ha-- starlings are thugs of the sky, apparently. i knew about the house sparrows edging out bluebirds bc i participate in a bluebird study with my Master Gardeners group, but i learned about starlings while filling in some gaps in my knowledge with this article: https://www.bbc.com/news/magazine-27055030
apparently ol' Eugene wanted to bring over every bird mentioned by Shakespeare...
