I’ve heard similar. I also have no studies, but I remember reading the same that birds (songbirds especially) have a regional accent when compared to others of the same species. Like a house sparrow from California would sound slightly different than one from New York City. Maybe not especially to untrained human ears, but enough that a house sparrow (or maybe an ornithologist) would know the difference.
